Aditya A 44b1fb3614 WL9513 Bug#23333990 PERSISTENT INDEX STATISTICS UPDATE BEFORE TRANSACTION IS COMMITTED ... PROBLEM By design stats estimation always reading uncommitted data. In this scenario an uncommitted transaction has deleted all rows in the table. In Innodb uncommitted delete records are marked as delete but not actually removed from Btree until the transaction has committed or a read view for the rows is present.While calculating persistent stats we were ignoring the delete marked records,since all the records are delete marked we were estimating the number of rows present in the table as zero which leads to bad plans in other transaction operating on the table. Fix Introduced a system variable called innodb_stats_include_delete_marked which when enabled includes delete marked records for stat calculations .		2017-04-24 17:45:23 +03:00
