Documents why a pipe fails on a MariaDB 12.3+ PARTIAL_ROW_DATA_EVENT and how to recover (resync, optionally raise binlog_row_event_fragment_threshold below max_allowed_packet). This anchor is referenced by the NOTIFY_BINLOG_PARTIAL_ROW_EVENT_UNSUPPORTED alert in clickpipes-platform. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

What
Adds a MySQL ClickPipes FAQ entry (anchor
#mariadb-partial-row-event-unsupported) explaining why a pipe fails when it encounters a MariaDB 12.3+PARTIAL_ROW_DATA_EVENT, and how to recover.Why
MariaDB 12.3+ fragments oversized row changes into
PARTIAL_ROW_DATA_EVENTs that a consumer must buffer and reassemble. ClickPipes doesn't support reassembly yet, so it now fails loudly (rather than silently dropping the row change) and requires a resync. The newNOTIFY_BINLOG_PARTIAL_ROW_EVENT_UNSUPPORTEDalert links users here.Mitigation documented
binlog_row_event_fragment_thresholdon the source to reduce fragmentation, keeping it belowmax_allowed_packet.Paired with clickpipes-platform PR (branch
fix/dbi-815/mysql-fail-on-maria-partial-row-data-event) which references this anchor.🤖 Generated with Claude Code
