When @@GLOBAL.gtid_strict_mode=1, then certain operations result in error that would otherwise result in out-of-order binlog files between servers. GTID sequence numbers are now allocated independently per domain; this results in less/no holes in GTID sequences, increasing the likelyhood that diverging binlogs will be caught by the slave when GTID strict mode is enabled.
