Research direction

Start by locating TiCDC's storage sink write paths and their existing error handling. Review current logging and documentation around sink failures, then define the retry strategy, backoff, limits, and error behavior. The work is done when failed writes retry as specified, attempts and backoff are logged, and the retry behavior is documented.
