Couchbase Kotlin SDK Release Notes and Archives

      Release notes for the Couchbase Kotlin Client.

      Version 1.1.0 (24 October 2022)


      • JVMCBC-1102: Added support for serverless execution environments including AWS Lambda.

      • KCBC-101: Added an experimental JSON serializer backed by kotlinx.serialization. See this sample code for usage and caveats.

      • KCBC-102: Added support for configuration profiles, which allow you to quickly configure an environment for common use-cases. In particular, this makes it easy to apply timeouts appropriate for WAN (Internet) development, such as developing against a remote Couchbase Capella instance. Example usage:

        val cluster = Cluster.connect(
            connectionString, username, password
        ) {
      • KCBC-105, 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.

      • KCBC-104: Changed AuthenticationFailureException error message to indicate that bucket hibernation is now a potential cause. Bucket hibernation is a feature coming in a future Couchbase release.

      • JVMCBC-1154: Bumped dependencies.

      Bug Fixes

      • JVMCBC-1141: Provide required OpenTelemetry span attributes.

      • JVMCBC-1155: Make sure targeted round-robin request keeps retrying if no config is available.

      Version 1.0.4 (9 September 2022)

      This maintenance release adds more cluster management APIs, and updates dependency versions.


      • KCBC-94: UserManager has a new changePassword function that lets you change the password of the currently authenticated user.

      • KCBC-99: Bucket has a new collections property of type CollectionManager. You can use the collection manager to create and delete scopes and collections. (Requires Couchbase Server 7.0 or later.)

      • KCBC-100: Added two new global config properties to help diagnose leaked Cluster instances. Cluster.maxAllowedInstances is the number of connected Cluster instances that may exist at the same time. Calling Cluster.connect after this limit is reached will either fail or log a warning, depending on the value of the new Cluster.failIfInstanceLimitReached property. The default values log a warning if more than 1 Cluster is connected at a time.

      • JVMCBC-1134: Updated MemcachedProtocol::decodeStatus to be inlineable.

      • JVMCBC-1135: Moved Core#reconfiguration off IO threads.

      • JVMCBC-1143: Failed telemetry spans will now record their exception and error status.

      • JVMCBC-1145: Updated maintenance dependencies.

      Version 1.0.3 (2 August 2022)

      Maintenance release.


      • JVMCBC-1116: Dependency versions have been increased.

      Bug Fixes

      • 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 bucket.waitUntilReady will not time out 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.

      Version 1.0.2 (6 July 2022)

      Maintenance release.

      Bug Fixes

      • JVMCBC-1103: To reduce overhead, the MAX_PARALLEL_FETCH value in KeyValueBucketRefresher has been updated to only fetch one config per poll interval.

      • JVMCBC-1104: Fixed issue where the global refresher did not honor the config poll interval.

      Version 1.0.1 (8 June 2022)

      Maintenance release.


      • KCBC-79: JacksonJsonSerializer now accepts the jackson ObjectMapper which for example makes it easier to use out of the box with Spring Boot.

      • JVMCBC-1093: Previously, when a DNS SRV lookup failure occurred, the SDK logged this as a WARNING along with a stack trace. The lookup failure is typically harmless, so the log message has now been downgraded to INFO level, without a stack trace.

      • JVMCBC-1088: Updated Netty to version 4.1.77.Final.

      Version 1.0.0 (3 May 2022)

      Initial GA release.
