Couchbase Scala SDK Release Notes and Archives

Release notes, installation instructions, and download archive for the Couchbase Scala Client.

These pages cover the 1.0 releases of the Couchbase Scala SDK, which follows the Couchbase 3.0 SDK API.

Version 1.0.2 (3 March 2020)

Version 1.0.2 is the third release of the Scala SDK, bringing enhancements and bugfixes over the last stable release.

The supported and tested dependencies for this release are:

  • com.couchbase.client:scala-client:1.0.2

  • com.couchbase.client:core-io:2.0.3

  • io.projectreactor:reactor-core:3.3.1.RELEASE

  • org.reactivestreams:reactive-streams:1.0.2


  • 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.

  • SCBC-43: With huge thanks to our community, who submitted the patch, it is now possible to build versions of the SDK for 2.11 and 2.13. Couchbase only officially provides, tests and supports a Scala 2.12 build currently, but users are welcome to build their own jars for 2.11 or 2.13 following the README instructions.

Bug Fixes

  • SCBC-200: Dependencies now correctly shaded.

  • SCBC-207: Exists no longer returns wrong value if executed right after remove.

  • SCBC-216: Properly clear cache when repreparing/retrying query.

  • JVMCBC-824: Native Netty transports not included, resulting in fallback to default implementation. This was a regression in the 2.0.2 core-io release.

  • JCBC-1600: Using expiry together with document flags on a Sub-Document mutateIn no longer causes an incorrect flags field to be sent.

Version 1.0.1 (5th February 2020)

Version 1.0.1 is the second release of the 1.0 series, bringing new features, enhancements, and bugfixes over the last stable release.

  • SCBC-192: All scaladoc warnings fixed.

  • SCBC-193: When creating buckets, numReplicas can now be specified.

New Features & Enhancements

  • SCBC-190: Exposed enableDnsSrv parameter on IoConfig(), allowing DNS SRV to be used.

  • SCBC-204: Added support for new server flag createAsDeleted — for internal use only.
