[jira] [Created] (IGNITE-17974) Clean up indexes on rollback

Konstantin Orlov created IGNITE-17974:
-----------------------------------------

             Summary: Clean up indexes on rollback
                 Key: IGNITE-17974
                 URL: https://issues.apache.org/jira/browse/IGNITE-17974
             Project: Ignite
          Issue Type: Improvement
            Reporter: Konstantin Orlov


To prevent indexes being bloated by orphan entries (entries with no matched rows in main storage), we need to perform some sort of clean up procedure in following cases: 
* Transaction has been rolled back, so we need to clean up all inserted and modified (which actually inserted from indexes point of view) rows 
* Row being consequently overwritten several times, so we need to clean up previously inserted intents

More details about clean up flow may be found in https://issues.apache.org/jira/browse/IGNITE-17673
