I’m glad to announce the release of Couchbase Elasticsearch Connector 4.0.1. This maintenance release improves the stability of the connector in rare cases where the Elasticsearch client library fails to serialize an incompatible document.
This release also introduces some new “uncommitted” configuration options:
- Support for environment variables in config files, useful for injecting configuration into Docker containers.
- Limited support for routing a document to a specific shard for use with Elasticsearch ‘join’ fields (caveat: deletions are ignored).
- Connector metadata can be stored in a bucket other than the one being replicated.
