MySQL CDC connector for ClickPipes is now Generally Available
↗
The MySQL CDC connector for ClickPipes, which replicates MySQL and MariaDB data into ClickHouse Cloud, is now Generally Available with parallel snapshotting, safer production defaults, and improved observability.
Engineers can now rely on a production-stable CDC path from MySQL to ClickHouse Cloud without building custom ETL. The GA release enforces GTID-based replication and 72-hour binlog retention at pipe creation, reducing the risk of irrecoverable replication failures that force full resyncs.

Parallel snapshotting now auto-detects partition keys from primary keys including string and UUID types, reducing a 1TB snapshot from over a day to roughly an hour across 32 workers.
New ClickPipes require GTID-based replication and at least 72-hour binlog retention, both validated at creation, to prevent replication failures on failover or extended pauses.
Existing file position-based pipes can coexist with GTID-based pipes, but ClickHouse recommends migrating legacy pipes to GTID.
