WITHOUT VALIDATION for EXCHANGE PARTITION/CONVERT IN

    XMLWordPrintable

Details

    Description

      Goal

      Add support for WITH VALIDATION | WITHOUT VALIDATION to
      ALTER TABLE ... EXCHANGE PARTITION ... WITH TABLE

      WITH VALIDATION should be the default behavior.

      Must also cover CONVERT {TABLE|PARTITION} TO

      Background

      When WITHOUT VALIDATION is specified, there is no check that all rows in the added table fulfills the partition restrictions. If there is inconsistencies, it will result in rows later not being found in SELECT, UPDATE or DELETE.

      MySQL has had this since 5.7.5 and it's important when adding big tables to a partitioned table to avoid the expensive row-by-row check.

      h3. Supplemental feature

      Make THAN keyword optional in partition definition of range partitioning.
