Conversation
…or types Adds deprecation callouts to docs pages for destination connectors that are deprecated and no longer actively maintained (Snowflake, ElasticSearch, Kafka including Confluent and Redpanda variants, Azure Event Hubs, Google Pub/Sub, S3, GCS, and BigQuery as a destination). BigQuery remains a supported source. Also marks the Query Replication (QRep) and XMIN mirror types as deprecated, recommending CDC as the actively-maintained mirror type. The callouts state these remain fully functional and that no code is currently being removed. Accompanies PeerDB-io/peerdb#4491. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
