# When the relay log gets rotated while the I/O thread
|
||||
# is reading a transaction, the transaction spans on two or more
|
||||
# relay logs. If STOP SLAVE occurs while the SQL thread is
|
||||
# executing a part of the transaction in the non-first relay logs,
|
||||
# we test if START SLAVE will resume in the beginning of the
|
||||
# transaction (i.e., step back to the first relay log)
|
||||
|
||||
# The slave is started with max_binlog_size=16384 bytes,
|
||||
# to force many rotations (approximately 30 rotations)
|
||||
|
||||
# We have to sync with master, to ensure slave had time to start properly
|
||||
# before we stop it. If not, we get errors about UNIX_TIMESTAMP() in the log.
