Release Notes

The GitHub releases page lists all the plug-in variants. In a given release, the plug-in’s filename is of the form elasticsearch-transport-couchbase-${PLUGIN_VERSION}-alder-es${ES_VERSION}.zip. It is imperative to use the file where ES_VERSION matches your Elasticsearch cluster version. For example, to use the 3.0.0 version of the plug-in with Elasticsearch 5.6.4, you will need to download elasticsearch-transport-couchbase-3.0.0-cypress-es5.6.4.zip.

Maintenance release for improved compatibility and stability.

The birch development line has been retired. The cypress line now supports all 5.x versions of Elasticsearch.

RegexParentSelector now reads the parent ID format from the correct config property (couchbase.parentSelector.documentTypesParentFormat.<type>). If you previously put the parent ID format in the documentTypeParentFields property as a workaround, please update your configuration.

The connector can now delete child documents and other documents that have custom routing. If you’re using RegexParentSelector then this feature has no additional overhead. Otherwise, for each document whose routing cannot be derived from the document ID, the connector creates a separate signpost document to record the routing. Be aware that child documents created by previous versions of the connector are not eligible for deletion, since they don’t have signposts (you’ll see "missing signpost" warnings in the log when the connector tries to delete those documents).

The signposts have a document type of couchbaseSignpost. The mapping for this type must store the contents of the meta field. This is already the case if you’re using the default mapping template included in the plugin distribution.

With this release, the Couchbase plug-in for Elasticsearch moves to a new versioning and branch management strategy that allows for simultaneous releases across ES versions (see Version Compatibility). All the versions are expected to work and are supported. However, versions which have received more testing and are officially supported are:

Don’t be alarmed by the major version bump; upgrading from version 2.x of the plug-in should be seamless, and is recommended for all users. The code has just been relabeled for easier maintenance.

This release note applies to the 2.1.1 version of the Elasticsearch Transport Plug-in (September 2015). It adds compatibility with newer Elasticsearch versions up to 1.7.x, multiple new features, and quite a few bug fixes, including several that solve issues found in 2.1.0. In particular, this release fixes a long-standing bug with an incorrect concurrent bulk request counter, which could eventually cause the plug-in to stop accepting requests from Couchbase Server altogether.

Some configuration option-names changed.
