ALTER TABLE ... DISCARD TABLESPACE takes a lot of time with large buffer pool (>128G)

Details

    • 10.1.29

    Description

      ALTER TABLE ... DISCARD TABLESPACE takes a lot of time with large buffer pool (>128G).

      Steps to reproduce:

      1. drop / create an InnoDB table
      2. discard the table space
      3. increase the buffer pool size.
      4. Re-try once you have a 128G+ buffer pool, and re-run #1 & #2.

      The discard time should be increasing.
