# ==== Purpose ====
#
# Issues START GROUP_REPLICATION on the current connection. Then waits
# until member state is ONLINE or the specified by
# $group_replication_start_member_state.

# ==== Usage ====
#

# [--let $group_replication_start_member_state= STATE]
# [--let $$wait_timeout= NUMBER]
# [--let $rpl_debug= 1]

#
# Parameters:
#   $group_replication_group_name
#     Group name
#
#   $group_replication_start_member_state
#     The state that the member must have after start, ONLINE
#     if not specified
#
#   $wait_timeout
#     See include/wait_condition.inc
