The replication slave SQL thread cannot keep up while processing row based events from the master's binary log. For example:
Several changes may cause this to start happening, for example:
- A new table without a primary key has been added to the system.
- The primary key was removed from an existing table.
- The binlog_format option was changed from STATEMENT to MIXED or ROW or from MIXED to ROW. See also <Note 1507802.1>.
- The workload changed with binlog_format = MIXED. When the format is set to MIXED, MySQL will automatically use the row based format, if the statement is considered potential non-deterministic.
