#BUG#16418100: ERROR "WHEN GTID_NEXT IS SET TO A GTID" ROW BASED REPLICATION
# Problem: When relay log info repository is configured to be persisted in a
# table and if a transaction that uses non-transactional engine is split across
# multiple relay logs, on relay log flush, partial transaction is
# committed. If the same situation occurs when gtid-mode=ON, it will cause that
# the same GTID will be used for more than one transaction and will cause
# ER_GTID_NEXT_TYPE_UNDEFINED_GROUP error.
#
# Steps to reproduce:
# 1) Generate two write_row events for non-transactional table (MyISAM)
# (Default binlog_row_max_event_size= 8192). Insert two tuples with tuple
# size as 8192 bytes each. This will generate two write_row events.
# 2) With Auto_position=0, stopping IO thread after receving one write_row
# event will split the transaction across two relay logs.
# 3) If relaylog_info_repository=table, SQL thread should be able to apply
# these type of relaylogs.
