classes.
storage/test_sql_discovery/test_sql_discovery.cc:
Let test_sql_discovery share class have unique name to avoid collision with
other classes.
Fixed sequence compilation failure.
storage/sequence/sequence.cc:
Adjusted sequence according to:
WL#4305 - storage-engine private data area per physical table.
Merge of 10.0-mdev26 feature tree into 10.0-base.
Global transaction ID is prepended to each event group in the binlog.
Slave connect can request to start from GTID position instead of specifying
file name/offset of master binlog. This facilitates easy switch to a new
master.
Slave GTID state is stored in a table mysql.rpl_slave_state, which can be
InnoDB to get crash-safe slave state.
GTID includes a replication domain ID, allowing to keep track of distinct
positions for each of multiple masters.
