This increases the efficiency for running REPLACE statements. Thanks to Jie Han for contributing the patch." ------------------------------------------------------------------------ [21 Jul 9:17] jie han we have billions records transfer from offline to online , rewrite replace statement will save lots of bytes. and rewirte to one sql means don't need explicitly begin transaction ,because one sql will execute in a standalone transaction when autocommit is true,this save two request for every batch. where network is slow autocommit will save more time. hope rewrite replace statement will release in next version. ------------------------------------------------------------------------ [20 Jul 17:27] Filipe Silva Bug#40561 is a duplicate of this. ------------------------------------------------------------------------ [12 Jul 8:00] Umesh Umesh Hello!
