[jira] [Created] (IGNITE-8207) SQL TX: Cleanup own previous changes on update

Anton Vinogradov (Jira)
Igor Seliverstov created IGNITE-8207:
----------------------------------------

             Summary: SQL TX: Cleanup own previous changes on update
                 Key: IGNITE-8207
                 URL: https://issues.apache.org/jira/browse/IGNITE-8207
             Project: Ignite
          Issue Type: Task
            Reporter: Igor Seliverstov


During update process we're cleaning up rows, which became invisible for all readers.

Updating a row more than once we are free to cleanup previous own changes except last one. This means we shouldn't leave more than two rows per key with version equal to current tx for updates and one for delete operations.
