The default tracing implementation, which tracks the top N slowest requests per service and dumps them at
configurable intervals.
The builder used to configure the
ThresholdLoggingTracer.Deprecated.
Deprecated.
The
TimeoutException signals that an operation timed out before it could be completed.The
Timer acts as the main timing facility for various operations, for
example to track and time out requests if they run for too long or for rescheduling needs.Configures the internal Timer, which asynchronous retries and timeouts fire on.
This event is raised if too many instances of the SDK are created as configured.
Raised if more SDK instances are created than allowed in configuration.
Generic exception that captures all tracer-related errors.
Holds static tracing and metrics identifiers throughout the SDK.
Contains various utils to set attributes for tracing spans.
Similar to the netty LoggingHandler, but it dumps the traffic into the event bus for later
consumption instead of logging it right away.
Emitted when the lost transactions cleanup process discovered a lost transaction and attempted to clean it up.
Emitted periodically with a summary of cleanup data since the last event.
Emitted periodically with a summary of what will be done soon for cleanup.
All transaction events derive from this.
Transactions does a lot of KV work from core-io.
Stores the transaction links stored on each document in a transaction
A transaction log message.
Used to indicate that we are inside a transaction, and placed in ThreadLocalStorage (or reactive context).
Used to manage ThreadLocalStorage (or reactive context) of TransactionMarker.
This operation (such as a replace, get or insert) either failed or ambiguously succeeded.
Handles cleaning up expired/lost transactions.
An event that's fired when transactions are successfully initialised.
This is a special case of the timeout exception, signaling that the timeout happened with no ambiguous cause.
During connecting to an endpoint, an exception/error was raised which was not expected.
This event is usually raised if the server closes the socket and the client didn't expect it.
This event is raised if the client detects an unknown SASL mechanism it cannot turn into an enum.
Requests implementing this interface will not be reported in various places.
Encodes and decodes the unsigned LEB128 (Little Endian Base 128) format.
If the server sends us unsolicited features during the HELLO negotiation,
this event will be raised - it is a warning severity since it indicates
a server bug.
Uses the KV "set" command to unconditionally replace or insert documents regardless if they
exist or not.
Indicates the target element is not intended for public use,
but some other Couchbase project depends on it.
Represents a user-agent for this client.
Common validators used throughout the client.
Subdocument exception thrown when the provided value cannot be inserted at the given path.
Represents a generic value recorder for the metrics interface.
Subdocument exception thrown when proposed value would make the document too deep to parse.
Thrown when the request is too big for some reason.
Parses the individual response http chunks for a view request.
The
ViewLocator extends the round-robin locator with some custom checks.There was a problem fulfilling the view request.
Helper class to perform the "wait until ready" logic.
Encapsulates the state of where a wait until ready flow is in.
The "wan-development" environment profile.
Raised if the watchdog in the core identifies an invalid state (and then tries to fix it).
Raised when the watchdog itself runs into an error that is logged.
TransactionOperationFailedException is raised as an opaque signal that something went wrong with a transaction
operation.
Subdocument exception thrown when the virtual attribute cannot be modified.
Deprecated.
Subdocument exception thrown when more than one xattr key has been requested.
Deprecated.
Subdocument exception thrown when an extended attribute cannot be accessed.
Subdocument exception thrown when a macro has been requested which is not recognised by the server.
