# Support to SKIP group gtid
#
# Case III - Support to skip gtid generated on multiple servers.
#
# Test:
# 0) The test requires two servers: M1 and M2.
# 1) With both members ONLINE in a group. GTID_EXECUTED must contain two
# transactions from view change events. Next sequence number is 3 on both the
# servers.
# 2) On M1 executes a transaction with GTID_NEXT=UUID_GROUP:3
# 3) On M2 execute a transaction, it will have:
# M1: UUID_GROUP:4
# M2: UUID_GROUP:4
# i.e. After this fix both servers should generate the same gtid (UUID_GROUP:4)
# 4) Check gtid_executed on M2. It must be UUID_GROUP:1-4.
# 5) Verify sequence of events in binlog of both M1 and M2.
# 6) Check gtid_executed on M1. It must be UUID_GROUP:1-4.
# 7) Clean up.
