Java SDK 3.7 Releases
We always recommend using the latest version of the SDK — it contains all of the latest security patches and support for new and upcoming features. All patch releases for each dot minor release should be API compatible, and safe to upgrade; any changes to expected behavior are noted in the release notes that follow.

, andfreezePlan
methods, which were not waiting for the server result before returning in the blocking API. -
JVMCBC-1480:
couchbase2:
should use exponential backoff when bypassingBestEffortRetryStrategy
. -
JVMCBC-1494: If you specify
min=1
for a Full-Text Search disjunction query, the SDK now always sends the value to the server. Previously, the SDK assumed1

The SDK now supports the new couchbase2 protocol, which is upcoming in future Couchbase Server versions.
It can be enabled through using a connection string starting with couchbase2://
.
Please see Cloud Native Gateway for more information.
The SDK now directly depends on SLF4J, which may impact some users — see below for details.

API Impacting
-
JVMCBC-1319: BEHAVIORAL CHANGE
As previously announced, the SLF4J API is now a required dependency, and the SDK does all logging through SLF4J. The following client settings for customizing logging behavior are deprecated, and no longer have any effect:
-
logger.disableSlf4J
-
logger.fallbackToConsole
-
logger.consoleLoggerFormatter
If your project does not already use SLF4J, please follow the announcement link for details and a mini-migration guide.
-
Improvements
-
JVMCBC-1402, JVMCBC-1410: Upgraded Netty from 4.1.96 to 4.1.100, and upgraded
OpenTelemetry
dependency. -
JVMCBC-1430: Optimization: removed creation of unnecessary metrics labels when default
LoggingMeter
is used. -
JVMCBC-1391: The Bucket Manager API is now forward-compatible with future versions of Couchbase Server that might support storage engine types other than "magma" and "couchstore".
-
JVMCBC-1327: Improved support for failover handling in future server versions.
Bugfixes
-
JVMCBC-1264: DNS SRV lookups now honor the DNS search path. This enables DNS SRV resolution in Kubernetes environments where the
*-srv
hostname advertised by the Couchbase Operator is a partial name that must be resolved using a suffix from the DNS search path. -
JVMCBC-1426: When Couchbase Server is too busy to start a new KV range scan, the SDK now retries instead of throwing a
CouchbaseException
.
Java SDK 3.4 Releases

,db.couchbase.collection
andoutcome
labels (tags). This new feature is at Stability.Volatile, and may change before it is promoted to Stability.Committed in a future release. -
JVMCBC-1311, JVMCBC-1352: Upgraded dependencies.
Bugfixes
-
JVMCBC-1350:
lookupInAnyReplica
now throwsFeatureNotAvailableException
if the server does not support the feature. -
JVMCBC-1351:
lookupInAnyReplica
no longer hangs when too many operations are specified. -
JVMCBC-1353: Removed the unrelocated
io.opentracing
classes that accidentally slipped into version 2.4.9 of the Couchbasecore-io
library. -
JVMCBC-1361: When the SDK receives multiple cluster map versions at the same time, it is now more careful about applying only the most recent version. Before this change, there was a brief window where the SDK could apply an obsolete cluster map. If this happened, the SDK would temporarily dispatch requests to incorrect or non-existent nodes. This condition was typically short-lived, and healed the next time the SDK polled for an updated cluster map, or dispatched a KV request to the wrong node.
-
JVMCBC-1368: Fixed a rare
java.lang.ArithmeticException: / by zero
exception inRoundRobinSelectionStrategy.select
that could occur during rebalance.
Version 3.4.9 (2 August 2023)
This release adds support for Sub-Document reads from replicas at @Stability.Volatile level: see collection.lookupInAnyReplica()

ReadTrafficCapturedEvent
now contains a single protocol frame, and the human-readable frame description is more accurate. -
JVMCBC-1320: The
waitUntilReady
method is now more aggressive about retrying failed pings. Also, waiting for a desired state ofDEGRADED
no longer fails when the client is fully connected to the cluster. -
JVMCBC-1343: Reduced the default value for the
io.idleHttpConnectionTimeout
client setting to 1 second. The previous default (4.5 seconds) was too close to the 5-second server-side timeout, and could lead to spurious request failures. -
JCBC-2078: Support for Sub-Document read from replica.

Improvements
-
JCBC-2077: Upcoming Couchbase server release 7.6 will support having SQL++ queries read from replicas, in scenarios where the active is unavailable (such as failover). This improves availability, though users should be aware that they may be reading stale data. The option is activated with
scope.query("…", queryOptions().useReplica(true))
, and is disabled by default. It will only work against 7.6 and above: against older server versions, it will raise aFeatureNotAvailableException
. -
JVMCBC-1322: The
waitUntilReady()
method now logs additional diagnostic information to thecom.couchbase.core.WaitUntilReady
logging category atDEBUG
level. -
JCBC-2059: If a
Cluster
becomes eligible for garbage collection, and you haven’t calledcluster.disconnect()
yet, the SDK now logs a warning and disconnects the cluster for you. This prevent the abandoned cluster’s network connections from living forever. Please do not rely on this "auto-disconnect" feature. It’s always better to callcluster.disconnect()
as soon as you’re done talking to the cluster, so the network connections and other resources get released right away. -
JCBC-2076:
Collection.touch
now has an additional overload that allows specifying the expiry as anInstant
instead of aDuration
.

API Impacting

JCBC-2075: Deprecated
ArrayInsert.createPath()
. Calling this method always causesmutateIn
to throw an exception, because the "array insert" sub-document command does not support creating missing parent objects. If you want to create missing parent objects, please useMutateInSpec.arrayAppend()
orarrayPrepend()
instead ofarrayInsert()
.
Improvements
-
JCBC-2069:
Collection.getAndTouch
now has an additional overload that allows specifying the expiry as anInstant
instead of aDuration
. -
JVMCBC-1290: Added a new environment config property,
SecurityConfig.enableCertificateVerification(boolean)
, which defaults to true. The purpose of this property is to allow disabling TLS certificate verification in development environments where configuring the CA certificate to trust is not practical. Setting this to false is equivalent to configuring the environment to useInsecureTrustManager.INSTANCE
. For compatibility with other modern Couchbase SDKs, certificate verification can now be disabled using the connection string parameter:tls_verify=none
. This config property is introduced at stability levelVolatile
, meaning it may change in a patch release without notice. -
JVMCBC-1278, JVMCBC-1310, JVMCBC-1313: Dependencies updated.
Bugs
-
JVMCBC-1283: A faceted Full-Text Search result’s
SearchNumericRange.min()
andmax()
methods now correctly return null instead of zero when the respective range endpoint is unbounded. -
JVMCBC-1288: Fixed a regression in Couchbase Java SDK 3.4.5 and Scala SDK 1.4.5 that prevented Full-Text Search result rows from including an explanation when requested.
-
JVMCBC-1292: Removed
META-INF/versions/9/module-info.class
from thecore-io
jar. This file was associated with an improperly repackaged dependency, and never should have been there.

objects. -
JVMCBC-1285: Fixed a regression in Couchbase Java SDK 3.4.5 and Scala SDK 1.4.5 that caused Full-Text Search queries to fail to report the locations of some terms. Specifically, any location that did not have

API stability level. A customRetryStrategy
can use this new, more granular information to distinguish if a connection problem is down to an authentication issue.
Bugs
-
JCBC-2032: The JSON returned by
SearchQuery.export()
no longer contains extra fields unrelated to the query. -
JVMCBC-1252: Orphaned "observe" operations will no longer occasionally contain a
total_duration_us
field equal to 0. -
JVMCBC-1255: If you were subscribing to the event bus and printing all the events, you may have noticed
Event.toString()

Improvements
-
JCBC-2050: Coordinates in Full-Text Search geographic queries can now be specified using a staged builder, so it’s harder to accidentally swap the latitude and longitude components. Example usage:
Coordinate eiffelTower = Coordinate.lat(48.858093).lon(2.294694);
Or, if you prefer to specify longitude first:
Coordinate eiffelTower = Coordinate.lon(2.294694).lat(48.858093);
-
JVMCBC-1237: Added "network" as an alias for the "io.networkResolution" connection string parameter. For example, the connection string "couchbase://example.com?network=external" is now equivalent to "couchbase://example.com?io.networkResolution=external". This was done for compatibility with other Couchbase SDKs that use "network" as the name of this parameter.
Bugs
-
JVMCBC-1232:
Cluster.connect()
now rejects connection strings that have no addresses (like "couchbase://"). Before this change, it would accept the invalid connection string, and subsequent operations would fail with a misleading error message: "The cluster does not support cluster-level queries". -
JVMCBC-1234: Fixed a regression in Java SDK 3.4.3 and Scala SDK 1.4.3 that caused SQL++ query result metadata to always include metrics, regardless of the "metrics" query option.

JCBC-2034:
CollectionQueryIndexManager
has been added at a@Stability.Volatile
level, to better allow management of query indexes at the Collection level. Documentation and an upgrade to a higher stability level will follow in the next minor SDK bump. Until then, users are encourage to try out the new functionality and provide feedback — but should expect the possibility of API changes. -
JVMCBC-1181: It is now possible to authenticate over secure connections even if the JVM does not support the SASL PLAIN authentication mechanisms.
-
JVMCBC-1184: Updated dependencies.
-
JVMCBC-1213: If too many operations are specified in a single sub-document lookup, the exception message now indicates why the operation failed.
Bug Fixes
-
JVMCBC-1160: When a sub-document path has a syntax error or is inappropriate for an operation, the SDK now throws
PathInvalidException
. Prior to this change, it would throw a genericCouchbaseException
with the message "Unexpected SubDocument response code". -
JCBC-2045:
WatchQueryIndexOptions
now extendsCommonOptions

Improvements

JVMCBC-1175: The SDK now includes native libraries for IO and TLS that can enhance performance on
aarch_64
architectures like Graviton and Apple Silicon. Previously, native libraries were included only forx86_64
architectures. Native libraries for IO and TLS are enabled by default. If you need to disable native IO, set theioEnvironment.enableNativeIo
client setting to false. To disable native TLS, set thesecurity.enableNativeTls
client setting to false.
Bugs
-
JVMCBC-1161: Fixed a minor issue where
cluster.disconnect()
could occasionally timeout due to a race condition. -
JVMCBC-1176: Setting
security.enableNativeTls
to false now prevents the SDK from even attempting to load the native TLS library. (Prior to this change, the SDK would load the library and just not use it.) In addition to saving a bit of memory, this prevents the JVM from segfaulting on Alpine Linux where glibc is not available. -
JVMCBC-1180: Supporting in transactions a future version of Couchbase Server that requires query_context be sent in all queries.
-
JVMCBC-1174: Fixed a regression that prevented native TLS from being used regardless of whether the
security.enableNativeTls
client setting was set to true.
Version 3.4.1 (7 December 2022)
Version 3.4.1 is the second release of the 3.4 series.
The headline change is support for the KV range scan feature (collection.scan()
), added at @Stability.Volatile level.
This feature will be available in a future version of Couchbase Server.
The supported and tested dependencies for this release are:
-

-
JVMCBC-1156: The traffic tracing functionality has been enchanced to perform Wireshark-style dissection of portions of the KV protocol.
-
JCBC-1984: KV range scan functionality (
collection.scan()
) added at @Stability.Volatile level. Users are encouraged to experiment with the feature and provide feedback ahead of its formal release in 3.5.0. -
JCBC-2018: Make Core and CoreEnvironment Autocloseable.
-
JCBC-2009: Fixed an issue where ArraySetOptions was extending CommonDatastructureOptions incorrectly.
-
JCBC-2021: Diagnostics for an endpoint now include the state of the endpoint’s circuit breaker.
-
JCBC-2027: The
ClusterEnvironment.Builder
methods that take aBuilder
are deprecated in favor of the overloads that take aConsumer<Builder>
. For example,ioConfig(IoConfig.Builder)
is deprecated in favor ofioConfig(Consumer<IoConfig.Builder>)
. The methods that take aConsumer<Builder>
are preferable because they allow customizing the config without clobbering the previous values. -
JCBC-2028:
Cluster.connect
now throws anIllegalArgumentException
if you pass a pre-builtClusterEnvironment
and a connection string incompatible with the environment. Before this change, an incompatibility was logged as a warning, and the connection string scheme and parameters were ignored.ConnectionStringIgnoredEvent
is now deprecated, since the SDK never publishes it anymore.-
A pre-built environment without TLS enabled is incompatible with a connection string that specifies the secure
couchases
scheme. -
A pre-built environment is incompatible with a connection string that has parameters.
-
-
JVMCBC-1159: Transactions now support upcoming server query_context changes.
Bugs
-
JVMCBC-1157: The SDK no longer rejects a
PersistTo
requirement in a bucket using the Magma storage engine. Before this change, the SDK would refuse the request because it misidentified Magma buckets as ephemeral (unable to persist documents). -
JVMCBC-1167: If you call
CancellationErrorContext.getWaitUntilReadyContext()
on an error context that didn’t come from a "wait until ready" request, the method is now guaranteed to return null instead of sometimes throwing aClassCastException
. -
JCBC-2024: Fixed a memory leak in ManagerMessageHandler.
-
JVMCBC-1247: The SDK now throws
InvalidArgumentException: Failed to parse connection string
if the connection string has a syntax error. For example, the following connection string is malformed, because thecouchbase://
part is repeated:couchbase://foo.example.com,couchbase://bar.example.com
. The correct way to include multiple addresses in a connection string is to specify the scheme only once, and to join addresses with commas, like:couchbase://foo.example.com,bar.example.com

JCBC-1979: A transactional
ctx.insert()
now consistently raises aDocumentAlreadyExistsException
if the document already exists. If this is caught, the transaction is now allowed to continue. -
JVMCBC-1144: If your Couchbase Server cluster’s root certificate is signed by a well-known certificate authority whose certificate is included in the JVM’s trust store, it’s no longer necessary to configure the certificate in the securityConfig settings.
-
JVMCBC-1154: Maintenance dependency bump.
Bugs

@Stability.Volatile
and could be subject to change. -
JVMCBC-1126: Updated metrics and tracing dependencies.
Bug Fixes
-
JVMCBC-1125: Fixed a rare

-
JCBC-1993: Fixed issue where a
NullPointerException
was thrown for a non-existent FTS index. -
JCBC-1955: Fixed a bug where concurrent transactions could hang due to scheduler starvation.

Improvements
-
JVMCBC-1116: Dependency versions have been increased.
-
JVMCBC-1121: In some rare cases — such as an application crash — a transaction is left for the async cleanup algorithm to finish; by default it will find this within one minute. In cases where this does not happen, this will trigger a warning after two hours — not the two days that was previously the case.
Bug Fixes
-
JVMCBC-1110: Transaction clients now reliably remove themselves from client records on shutdown.
-
JVMCBC-1119: The num (kv) nodesExt to equal number of nodes check can lead to otherwise healthy clusters being flagged as not ready. The check has been removed, and now the ` Bucket
waitUntilReady
will not timeout on these edge cases. -
JVMCBC-1120:
ClusterConfig#allNodeAddresses
now takes global config into account — avoiding the triggering of some unnecessary reconfigurations. -
JVMCBC-1112: Deprecated Reactor Processors have been replaced.
-
JVMCBC-1115: The SDK now allows for configurations with only TLS ports.

along with a stack trace. The lookup failure is typically harmless, so the log message has now been downgraded toINFO
level, without a stack trace. -
JVMCBC-1088: Updated Netty to version

.
Version 3.3.0 (26 April 2022)
Version 3.3.0 is the first release of the 3.3 series.
The three headline changes in this release:
-
Supports the new functionality of Couchbase Server 7.1.
-
Directly integrates transactions into the SDK rather than requiring a separate library. Existing users of the transactions library can refer to the Distributed Transactions Migration Guide to see the simple steps needed to migrate, which we recommend.
-
Bundles the public server security certificates for Couchbase Capella, to make it easier for users to get started with Capella.

Bugs
-
JVMCBC-1060: Fixed an issue where rate limited exceptions were not thrown for
SearchIndexManager
errors. -
JVMCBC-1071: The SDK now ensures that negative values are not sent to the
ValueRecorder
. -
JCBC-1918: Executing a Full-Text Search query with an open-ended date range facet no longer results in a
NullPointerException
. -
JCBC-1919: Index fields are now quoted in the analytics index manager.
-
JCBC-1921: QueryIndexManager
buildDeferredIndexes
no longer throws aParsingFailureException
against Couchbase Server 6.0.
New Features
-
JVMCBC-1057: Added core infrastructure for the Backup service. Users can now make custom HTTP requests to the Backup service.
-
JVMCBC-1064: When implementing a custom
RetryStrategy
, a new overload ofRetryAction.noRetry
lets you specify an exception translator for converting the default request cancellation exception into your preferred exception class.
Improvements
-
JVMCBC-1065:
RetryReason.allowsNonIdempotentRetry()
is now public, so you can call it from a customRetryStrategy
. -
JVMCBC-1066: When
SecurityConfig.Builder.trustCertificate(Path)
is given a file containing more than one certificate, it now trusts all the certificates instead of just the first one. Likewise, the result ofSecurityConfig.decodeCertificates(List<String>)
now includes all certificates in each string, not just the first certificate in each string. -
JVMCBC-1068: Added explicit handling of
FeatureNotAvailable
for Magma on CE. -

ClusterEnvironment
without having to build and shut down the environment. The newClusterOptions.environment(Consumer<ClusterEnvironment.Builder>)
method lets you configure properties of aClusterEnvironment
owned by the Cluster, so you don’t need to manage the environment yourself. Example usage:
Cluster cluster = Cluster.connect("localhost", clusterOptions(username, password) .environment(env -> env.ioConfig().captureTraffic(ServiceType.MANAGER)));

Version 3.1.1 (12 January 2021)
Version 3.1.1 is the second release of the 3.1 series, bringing stabilizations and enhancements over 3.1.0.
The supported and tested dependencies for this release are:
-
com.couchbase.client:java-client:3.1.1
-
com.couchbase.client:core-io:2.1.1
-
io.projectreactor:reactor-core:3.4.1
-
org.reactivestreams:reactive-streams:1.0.3
API Affecting
-
JVMCBC-906: Removed Tracer as a mandatory argument from
OpenTelemetrySpan
. (The OpenTelemetry module is marked@Stability.Volatile
, indicating that there may be API-breaking changes. The volatility arises from the underlyingOpenTelemetry
library itself being at a beta/volatile level.)
Bugs
-
JVMCBC-909: Retry opening the bucket until timeout when it is not found, to allow for it not yet being created.
-
JVMCBC-910: WaitUntilReady will now wait if bucket not present yet, before it starts to time out.
-
JVMCBC-911, JCBC-1728: Certain collection-related error codes have changed.
-
JCBC-1730: Support for collections added to
BatchHelper
. -
JCBC-1747: Prepared non-adhoc queries on scopes were failing, as query_context was not being passed to the individual prepare and/or execute statements. This has now been fixed, and scope-level queries are working as expected.
Enhancements
-
JVMCBC-907: The Orphan Reporter can now be disabled.
-
JVMCBC-908: Updated OpenTelemetry to 0.13.
-
JCBC-1749: Escape the scope for scope-level queries now enabled, as a fix in the server means that this works.
-
JCBC-1746: Expose partition information from the query management API on
QueryIndex
class.
Version 3.1.0 (2 December 2020)
Version 3.1.0 is the first GA release of the 3.1 series, bringing stabilizations and enhancements over 3.0.10 and the 3.0 SDK, and adding features to support Couchbase Server 6.6 and 7.0β.

-
io.projectreactor:reactor-core:3.4.0
-
org.reactivestreams:reactive-streams:1.0.3
Enhancements
-
JCBC-1731: Experimental support for Metrics (
Meter
) and the internals have been reworked around theRequestTracer
. The new metrics implementation is disabled by default but will be enabled in the future. We encourage you to try it out and provide feedback, please see the documentation section on tracing and metrics for further information. -
JCBC-1646: The minimum durability level can now be configured on the
BucketManager
. -
JVMCBC-904: Internal and external dependencies have been updated, including project reactor to
3.4.0
. -
JVMCBC-905: It is now possible to disable TLS hostname verification as part of the
SecurityConfig

In addition to the tickets outlined below, different interfaces have been elevated from Uncomitted
or Volatile
to Comitted
. These include:
-
Expiry Key/Value read and write APIs that take an
Instant
. -
Geo-Polygon Search
-
Search Flex-Index Option
-
Search Disable-Scoring Option
Java SDK 3.0 Releases
Version 3.0.10 (3 November 2020)
Version 3.0.10 is a maintenance release, bringing enhancements over the last stable release.
The supported and tested dependencies for this release are:
-
com.couchbase.client:java-client:3.0.10
-
com.couchbase.client:core-io:2.0.11
-
io.projectreactor:reactor-core:3.3.9.RELEASE
-
org.reactivestreams:reactive-streams:1.0.3
Enhancements
-
JVMCBC-898: Added fallback for lastDispatchedTo in context, to improve debuggability.
-
JVMCBC-899: Updated OpenTelemetry to 0.9.1.
Version 3.0.9 (7 October 2020)
Version 3.0.9 is a bugfix release of the 3.0 series, bringing enhancements and bugfixes over the last stable release.
The supported and tested dependencies for this release are:
-
com.couchbase.client:java-client:3.0.9
-
com.couchbase.client:core-io:2.0.10
-
io.projectreactor:reactor-core:3.3.9.RELEASE
-
org.reactivestreams:reactive-streams:1.0.3
API Affecting
-
JCBC-1716: The Analytics getPendingMutations API had a return value (
Map<String, Long>
) that did not reflect what was returned from the server. The return value has been changed toMap<String, Map<String, Long>>
accordingly. As the getPendingMutations method was previously uncallable due to the resulting deserialization failure, we believe this API change - though technically breaking - will not impact any users, and we have kept the API version at 3.x.
Bug Fixes
-
JCBC-1713: Improve LDAP auth failure handling.
-
JCBC-1718:
Expiry
fixed fortouch
andgetAndTouch
methods. -

-
JVMCBC-894: BatchHelper: handle success case with no body gracefully.
-
JVMCBC-872: Subdoc 'no access' error code is now reported correctly. This helps users to identify and fix permissions errors for system XATTRs.
Enhancements
-
JCBC-1651: Geopolygon search support.
-
JCBC-1652: Added Options To Use FTS Hints (Flex Index).
-

-
JVMCBC-886: Improve LDAP auth failure handling.
-
JVMCBC-896: Fast dispatch pooled requests.

com.couchbase.client:java-client:3.0.8
-
com.couchbase.client:core-io:2.0.9
-
io.projectreactor:reactor-core:3.3.9.RELEASE
-
org.reactivestreams:reactive-streams:1.0.3
Enhancements
-
JCBC-1705: A (uncomitted) API has been added which allows to very efficiently perform bulk fetch and bulk exists operations. See the
BatchHelper
class for more details. -
JCBC-1684: The
PingOptions
services can now be configured through a vararg, making it easier to use. -
JCBC-1691: A (uncomitted) API has been added which allows sending all kinds of requests to the cluster manager (called raw manager API).
-
JVMCBC-883: The client is now a little less verbose when performing a DNS SRV request and the underlying JDK operation times out.
-
JVMCBC-879: Updated internal and external dependencies to their latest maintenance releases.
-
JVMCBC-871: On the
IoConfig
it is now possible tocaptureTraffic()
with empty arguments, implying that all traffic will be captured. -
JVMCBC-874: When dealing with unknown collections, the SDK now returns a more user friendly retry reason when it can (outdated manifest vs. collection not found).
-
JVMCBC-875: On the request timeout exception, the retry reasons are now accessible directly.
-
JCBC-1693: The
UserManager
API has been extended to support collections and scopes (needs at least Server 7.0 to be usable). -
JCBC-1660: Support for scope-level SQL++ queries has been added (needs at least Server 7.0 to be usable).
-
JCBC-1658: Support for scope-level analytics queries has been added (needs at least Server 7.0 to be usable).
Bug Fixes
-
JCBC-1696: When adding the option
withExpiry(true)
toGetOptions
, it is now possible to use a custom transcoder which is JSON compatible. -
JVMCBC-805: The client now handles bootstrapping against nodes much better which do not have the data service enabled (in an MDS setup).
-
JVMCBC-882: A bug has been fixed where when bootstrapping against a node with no data service enabled, the endpoint would not be cleaned up and would keep trying to reconnect.
-
JVMCBC-872: The client now more explicitly handles an error response code (
NO_ACCESS
) when a subdocument request is performed against a system xattr. -
JVMCBC-873: Durability information is now properly unwrapped from an optional when exported and dumped (for example as part of an exception).
-
JVMCBC-880: The client now trackes multiple parallel bucket open attempts (against different buckets) in a better way, making sure that an internal state is only switched when all those bucket open attempts have completed (and not just the first one).
-
JVMCBC-878:
EndpointDiagnostics
had the local and remote hostnames mixed up, they now show up in the correct order.
Version 3.0.7 (4 August 2020)
Version 3.0.7 is the eighth release of the 3.0 series, bringing enhancements and bugfixes over the last stable release.
The supported and tested dependencies for this release are:
-
com.couchbase.client:java-client:3.0.7
-
com.couchbase.client:core-io:2.0.8
-
io.projectreactor:reactor-core:3.3.8.RELEASE
-
org.reactivestreams:reactive-streams:1.0.3
Bug Fixes
-
JCBC-1647: Deprecated
EjectionPolicy
in favor ofEvictionPolicyType
. And added the "noEviction" and "nruEviction" policies used by ephemeral buckets. This fixed a but where the BucketManager didn’t recognize ephemeral bucket ejection values. Users can now set a non-default ejection policy when creating an ephemeral bucket. -
JCBC-1668: Fixes an NPE when
toString
orfieldsAs
is called when no fields are present in the result. In this case just null should now be returned, instead of a NPE deep down in the Jackson serializer stack. -
JVMCBC-870: A bug in the chunk response parser prohibited responses meant that View reduce responses were never completed, and as a result timed out on the user side. The completion of view results with reduce enabled has now been fixed.
Enhancements
-
JCBC-1661, JCBC-1665: Building on the expiry improvements in the previous release, this adds a new
expiryTime()
method that returns expiry as anInstant
, which better expresses the concept than theDuration
returned byexpiry()
. The latter will be deprecated in a future release. Similarly, everywhere aDuration
-based expiry could be provided previously, an overload has been added to take anInstant
-based expiry. -
JCBC-1666: Made
bucket.scope("_default").collection("_default")
behave just likebucket.defaultCollection()
.AsyncScope.collection()
now no longer refreshes collection map for default collection. -
JCBC-1670: Added WaitUntilReadyOptions.serviceTypes() overload that accepts varargs.
-
JVMCBC-867: Performance improvement: do not grab ByteBuf slice when extracting server response time.
-
JVMCBC-869: Maintenance dependency bump: Netty → 4.1.51, Jackson → 2.11.1, Reactor → 3.3.7, OpenTelemetry → 0.6.0.
Version 3.0.6 (14 July 2020)
Version 3.0.6 is the seventh release of the 3.0 series, bringing enhancements and bugfixes over the last stable release.
The supported and tested dependencies for this release are:
-
com.couchbase.client:java-client:3.0.6
-
com.couchbase.client:core-io:2.0.7
-
io.projectreactor:reactor-core:3.3.5.RELEASE
-
org.reactivestreams:reactive-streams:1.0.3
Enhancements
-
JCBC-1645: Specifying document expiries has been made significantly easier. Expiries are supplied as a
Duration
. The new behaviour is that if that duration is less than 50 years, then it will be interpreted as being a relative timestamp from the current time. E.g.Duration.ofDays(35)
will expire in 35 days time. (Previously, aDuration
longer than 30 days would be interpreted as being an epoch time. Unless this epoch time occurred in the future then it would expire immediately. In order to preserve compatibility for users that worked around this behaviour, anyDuration
longer than 50 years will continue to be interpreted as an epoch time.) -
JCBC-1632: Bootstrapping is now fully pipelined for performance, building on the improvements in the previous release.
-
JVMCBC-865: Changed the default idle timeout to 4.5s for http connections, to support performance improvements in query service.
Bug Fixes
-
JCBC-1662:
MutateInMacro
for CRC32 is fixed. -
JCBC-1664:
viewQuery
withViewOptions.viewOptions().keys(keys)
was returning a bad_request error. This is now fixed. -
JVMCBC-849: Redundant global loading exceptions no longer propagated — now logged at
debug
level. -
JVMCBC-856: A just-opened connection in pool no longer gets cleaned up prematurely .
-
JVMCBC-858: Channel writeAndFlush failures are no longer ignored.
-
JVMCBC-862: Race condition with node identifier change on bootstrap identified. New logic and some changes to the config provider code ensures that retry and resubscribe picks up fresh seed nodes.
-
JVMCBC-863: Bucket-Level ping report no longer includes other view and KV services buckets.
-
JVMCBC-866: Trailing : no longer added to IPv6 addresses without []. 'invalid IPv6 address' warnings now no longer produced when trying to connect to a valid Ipv6 address thus specified.
Version 3.0.5 (2 June 2020)
Version 3.0.5 is the sixth release of the 3.0 series, bringing enhancements and bugfixes over the last stable release.
The supported and tested dependencies for this release are:
-
com.couchbase.client:java-client:3.0.5
-
com.couchbase.client:core-io:2.0.6
-
io.projectreactor:reactor-core:3.3.5.RELEASE
-
org.reactivestreams:reactive-streams:1.0.3
Enhancements
-
JVMCBC-852: Bumped Reactor to 3.3.5, Netty to 4.1.50.Final, and Jackson to 2.11.0.
-
JVMCBC-693: For performance, the KV bootstrap sequence is now partially pipelined.
In addition, there are internal revisions to support the forthcoming Field Level Encryption (FLE) support. This will be available in a separate library for Enterprise Edition subscribers.
Bug Fixes
-
JVMCBC-851: Reactive getAllReplicas methods will now honor a provided custom transcoder.
-
JVMCBC-849: Duplicate global loading exceptions are now swallowed to remove redundant warnings from logging (this was a cosmetic-only issue).
Version 3.0.4 (7 May 2020)
Version 3.0.4 is the fifth release of the 3.0 series, bringing enhancements and bugfixes over the last stable release.
The supported and tested dependencies for this release are:
-
com.couchbase.client:java-client:3.0.4
-
com.couchbase.client:core-io:2.0.5
-
io.projectreactor:reactor-core:3.3.4.RELEASE
-
org.reactivestreams:reactive-streams:1.0.3
Enhancements
-
JVMCBC-841: Bumped Netty dependency to 2.0.30, and reactor to 3.3.4
Bug Fixes
-
JVMCBC-845: If a rebalance is stopped in the middle, an edge case occasionally causes KV ops to time out as the fast forward map is chosen over the retry. The behavior has now been changed so that the client will try the old and new servers to make sure the operation eventually gets dispatched to the right node.
-
JCBC-1626: If bucket is not flushable, a
BucketNotFlushableException
is now raised.
Version 3.0.3 (7 April 2020)
Version 3.0.3 is the fourth release of the 3.0 series, bringing enhancements and bugfixes over the last stable release.
The supported and tested dependencies for this release are:
-
com.couchbase.client:java-client:3.0.3
-
com.couchbase.client:core-io:2.0.4
-
io.projectreactor:reactor-core:3.3.3.RELEASE
-
org.reactivestreams:reactive-streams:1.0.2
Enhancements
-
JCBC-1603, JCBC-1606: Exposed API to set the CollectionsExample TTL. CreateCollection CollectionSpec now includes
MaxTTL
. -
JCBC-1617: Attempting to work with the collection manager on clusters where CollectionsExample are not available (or enabled as a DP) will now result in a
FeatureNotAvailable
failure. -
JVMCBC-830: Added more convenient overloads for SecurityConfig and CertAuth. These overloads initialize both the SecurityConfig and the CertificateAuthenticator directly from a KeyStore or TrustStore.
-
JVMCBC-831: Improves timeout for waitUntilReady — the
waitUntilReady
helper should now throw a proper timeout exception. -
JVMCBC-832: Added support for multiple ports per hostname in the connection string — without having to use the explicit SeedNode set overload.
-
JVMCBC-835: Using "localhost:8091" as a connection string would set the kv bootstrap port to 8091, which is not desired behavior. To prevent this from happening again, the code now checks for this condition, fails fast, and also provides guidance on what the connection string should look like instead.
-
JVMCBC-836: Enabled Unordered Execution by Default.
-
JVMCBC-837: Updates OpenTelemetry to 0.3 (beta).
Bug Fixes
-
JCBC-1618: Named fields in SearchRows results are now deserialized.
-
JVMCBC-834: 'CollectionNotFoundException' now triggers a retry, and if no collection refresh is currently in progress it will proactively trigger a new one. Now Docs created under custom collection should no longer raise an exception when a collection has been created in the meantime, but the collection is not found as no refresh is in progress.
-
JVMCBC-826: A NullPointerException was occuring when LDAP is enabled. The code now explicitly fails the connection with a descriptive error message instructing the user what to do next (either use TLS which is preferred) or enable PLAIN on the password authenticator (insecure).
-
JVMCBC-827: Search query results row_hit typo resulted in 0 being returned for total rows. This has now been fixed.
-
JVMCBC-828: Omit internal config request in orphan reporting.
-
JVMCBC-839: Bootstrap will now correctly use the mapped port if alternate addr is present.
Version 3.0.2 (3 March 2020)

JCBC-1588: Give TypeRef overload of JsonSerializer a default "unsupported" impl, making it easier for applications to implement custom JsonSerializers.
-
JVMCBC-813: Improved error message for bucket is missing.
-
JVMCBC-815: Check if key exceeds size limits.
-
JVMCBC-818: Trimmed netty stack in connect failures for more readable output.
-
JVMCBC-819: Distinguished bucket not found in select bucket failures.
-
JVMCBC-823: Added a global component to the core id.
-
JVMCBC-825: Support added for new VATTR HELLO flag.
Bug Fixes
-
JCBC-1587: Exists no longer returns wrong value if executed right after remove.
-
JCBC-1600: Using expiry together with document flags on a Sub-Document
mutateIn
no longer causes an incorrect flags field to be sent. -
JCBC-1604: Properly clear cache when repreparing/retrying query.
-
JVMCBC-824: Native Netty transports not included, resulting in fallback to default implementation. Only affected 2.0.2 core release.
Version 3.0.1 (5 February 2020)
Version 3.0.1 is the second release of the 3.0 series, bringing enhancements and bugfixes over the last stable release.

com.couchbase.client:core-io:2.0.2
-
io.projectreactor:reactor-core:3.3.1.RELEASE
-
org.reactivestreams:reactive-streams:1.0.2
Enhancements
-
JCBC-1578: Added support for Java Object Serialization as a custom
Transcoder
. -
JVMCBC-808: The internal packaged
netty
dependency has been reduced to the minimum amount of artifacts needed, trimming the resulting jar size a little.
Bug Fixes
-
JCBC-1574:
JsonObject/Array.put(String,Object)
now supports writing generic Maps and Lists. -
JCBC-1580: The code for get projections had an import for unbundled jackson which prevented it from working in an environment where no unbundled jackson is on the classpath. This no longer occurs.
-
JCBC-1582: The client context ID is now propagated into the
PREPARE
query if needed. -
JVMCBC-806: TLS: remote hostname and port are passed down to the SSL engine, making sure that hostname validation works as expected.
-
JCBC-1575: Bucket Management: BucketSettings load does now recognize numReplicas properly.
Known Issues
-
JVMCBC-805: When bootstrapping against a non-KV node the KV socket is not cleaned up properly. As a workaround (and as we recommend in general), please only bootstrap against nodes which have the KV service enabled. Or maintain a list of KV nodes in DNS SRV.
