Couchbase connector updated to version 4.3.6

The Couchbase connector for Aiven for Apache Kafka® Connect is updated from version 4.1.11 to 4.3.6.

Behavior change

The auto network detection fallback behavior has changed. The connector now selects the external network when no exact address match exists and the external network is present.

If the connector fails to connect after the update, add the following to the connector configuration:

couchbase.network=default

Security

This update improves validation and error handling for Couchbase TLS certificate paths to prevent sensitive information from being written to connector logs.

Other changes

• Adds per-topic configuration overrides for key sink properties.
• Adds multi-bucket write support for the sink connector.
• Deprecates couchbase.topic.to.collection and couchbase.topic.to.document.id. Use couchbase.default.collection and couchbase.document.id with contextual overrides instead.
• Fixes a startup race condition that could cause ConcurrentModificationException.
• Updates the Couchbase Java SDK to 3.11.3.
