# ==== Purpose ====
#
# Switch GTID_MODE on all servers or on a subset of them. Step on all
# servers simultaneously, so that replication does not need to stop.
#
# Optionally, sync replication first.
#
# This works even if rpl_init.inc has not been invoked; in that case
# it assumes there is only one server running.
#
# ==== Usage ====
#
# [--let $rpl_gtid_mode= [OFF|OFF_PERMISSIVE|ON_PERMISSIVE|ON|0|1|2|3]]
# [--let $rpl_set_enforce_gtid_consistency= [0|1]]
# [--let $rpl_server_numbers= [X[,Y[,Z...]]]
# [--let $rpl_skip_sync= 1]
# [--let $rpl_only_running_threads= 1]
# [--let $rpl_debug= 1]
# [--let $no_extra_info= 0]
# --source include/rpl_set_gtid_mode.inc
#
# Parameters:
# $rpl_gtid_mode= [OFF|OFF_PERMISSIVE|ON_PERMISSIVE|ON|0|1|2|3]
# By default, switches to ON. Set this to switch to any other mode.
#
# $rpl_set_enforce_gtid_consistency
# By default, leaves ENFORCE_GTID_CONSISTENCY unchagned. If this is
# set, changes ENFORCE_GTID_CONSISTENCY to the specified value.
#
# $rpl_server_numbers= [X[,Y[,Z...]]]
# By default, switches GTID_MODE on all servers configured by
# rpl_init. Set $rpl_server_numbers to a comma-separated list if
# you want to switch on a specific subset of the servers.
#
# $rpl_skip_sync
# By default, all slaves are synced using rpl_sync.inc. Set this
# option to 1 to disable this behavior (note that you must
# manually sync all servers in this case). Normally you want to
# sync, but you need to disable sync if you use multi-source.
#
# $rpl_only_running_threads
# See include/rpl_sync.inc
#
# $rpl_debug=1
# See include/rpl_init.inc
#
# $no_extra_info=0
# Do not print the mode and server after the include file name. This option
# allows to easly support tests that may invoke with dynamic parameter
# values.
