Purges happen at startup and at + binary log rotation. + --binlog-format=name + What form of binary logging the master will use: either + ROW for row-based binary logging, STATEMENT for + statement-based binary logging, or MIXED. MIXED is + statement-based binary logging except for those + statements where only row-based is correct: those which + involve user-defined functions (i.e. UDFs) or the UUID() + function; for those, row-based binary logging is + automatically used. If NDBCLUSTER is enabled and + binlog-format is MIXED, the format switches to row-based + and back implicitly per each query accessing an + NDBCLUSTER table + --binlog-group-commit-sync-delay=# + The number of microseconds the server waits for the + binary log group commit sync queue to fill before + continuing.

'MINIMAL', means that a PK + equivalent (PK columns or full row if there is no PK in + the table) is logged in the before image, and only + changed columns are logged in the after image. (Default: + FULL). + --binlog-row-metadata=name + Controls whether metadata is logged using FULL or MINIMAL + format. FULL causes all metadata to be logged; MINIMAL + means that only metadata actually required by slave is + logged. Default: MINIMAL. + --binlog-row-value-options=name + When set to PARTIAL_JSON, this option enables a + space-efficient row-based binary log format for UPDATE + statements that modify a JSON value using only the + functions JSON_SET, JSON_REPLACE, and JSON_REMOVE.
