checkpoint can miss transactions with commit times before stable

    XMLWordPrintableJSON

Details

    Description

      There's a window where a checkpoint can fail to include a transaction's updates with commit times before stable. If:

      1. the commit timestamp is checked at transaction commit and the transaction sleeps
      2. stable is then moved past the commit timestamp
      3. checkpoint selects a stable timestamp and runs

      The checkpoint will not include changes for a commit timestamp that is before the checkpoint's stable timestamp.
