# Support to SKIP group gtid
#
# CASE IV - Test for the gtid event generated during view change event.
#
# The GTID generated during VIEW_CHANGE should also skip the already executed
# group_gtid to avoid error.
#
# Test:
# 0) The test requires two servers: M1 and M2.
# 1) Bootstrap start a group on M1.
# 2) On M1 execute a transaction with GTID_NEXT=UUID_GROUP:2. M1 will have:
# GTID EXECUTED = UUID_GROUP:1-2.
# 3) Start GR on M2.
# 4) Check gtid_executed=UUID_GROUP:1-3 on M1.
# 5) Verify sequence of events in binlog on both M1 and M2.
# 6) Check gtid_executed=UUID_GROUP:1-3 on M2.
# 7) Clean up.
