Supreetha-V opened a new pull request, #4182:
URL: https://github.com/apache/flink-cdc/pull/4182
Summary:
Improves MySQL CDC connector reliability by adding proper handling for
authentication failures during binlog client reconnection attempts.
Problem:
When credential rotation occurs in MySQL, the binlog client may fail to
reconnect silently, causing the CDC connector to stop processing changes
without proper error reporting.
Changes
- Added connection health checks in the binlog streaming loop
- Added specific handling for AuthenticationException during reconnection
- Improved logging to provide clear feedback on connection status and
failures
