# bug#31552 Replication breaks when deleting rows from out-of-sync table

|
|
# The default for slave-exec-mode option and server

# variable slave_exec_mode is 'STRICT'.

# When 'STRICT' mode is set, the slave SQL thread will stop whenever

# the row to change is not found. In 'IDEMPOTENT' mode, the SQL thread
|

# will continue running and apply the row - replace if it's Write_rows event -
