The actively-maintained destinations are ClickHouse, ClickHouse Cloud, and Postgres. The destinations marked (deprecated) below (Snowflake, ElasticSearch, Kafka including the Confluent and Redpanda variants, Azure Event Hubs, Google Pub/Sub, S3, GCS, and BigQuery) are deprecated and no longer actively maintained. They remain fully functional and no code is currently being removed. BigQuery is deprecated only as a destination; it remains a supported source.Streaming Query Replication (QRep), including XMIN-based replication, is also a deprecated mirror type. We recommend CDC (Change Data Capture) as the actively-maintained mirror type for new mirrors.
Below table shows supported source and target connectors for Real-time Change Data Capture and Streaming Query Replication. ✅ means supported. ⚠️ means beta. 🛑 means unsupported. N/A means Not Applicable
