# ==== Purpose ====
|
|
#
|
|
# Save the current position of the IO thread, just like
|
|
# save_master_pos.inc does for the master's position.
|
|
#
|
|
#
|
|
# ==== Usage ====
|
|
#
|
|
# [--let $use_gtids= 1]
|
|
# [--let $rpl_debug= 1]
|
|
# --source include/save_master_pos.inc
|
|
#
|
|
# Typically, you would use this script together with
|
|
# include/sync_io_with_master.inc
|
|
#
|
|
# Parameters:
|
|
#
|
|
# $use_gtids
|
|
# By default, this script saves the binlog file and offset. If
|
|
# $use_gtids is set, this script saves the gtids.
|
|
#
|
|
# $rpl_channel_name
|
|
# Uses this channel name rather than the default channel.
|
|
#
|
|
# $rpl_debug
|
|
# See include/rpl_init.inc
|
