------------------------------------
Summary: Trigger compaction with old aborted txns
Key: HIVE-23280
URL: https://issues.apache.org/jira/browse/HIVE-23280
Project: Hive
Issue Type: Improvement
Reporter: Karen Coppage
Assignee: Karen Coppage
When a txn is aborted and the compaction threshold for number of aborted txns
is not reached then the aborted transaction can remain forever in the RDBMS
database. This could result in several serious performance degradations:
- getOpenTxns has to list this aborted txn forever
- TXN_TO_WRITE_ID table is not cleaned
We should add a threshold, so after a given time the compaction is started
anyway.
