-------------------------------------
Summary: CompactionTxnHandler.cleanEmptyAbortedTxns() should
safeguard against huge IN clauses
Key: HIVE-12389
URL: https://issues.apache.org/jira/browse/HIVE-12389
Project: Hive
Issue Type: Bug
Components: Metastore, Transactions
Affects Versions: 1.0.0
Reporter: Eugene Koifman
Assignee: Eugene Koifman
in extreme situations, due to misconfigurations, it may be possible to have
100Ks or even 1Ms of aborted txns.
This causes delete from TXNS where txn_id in (...) to have a huge IN clause and
DB chokes.
Should use something like TxnHandler.TIMED_OUT_TXN_ABORT_BATCH_SIZE to break up
delete into multiple queries. (Incidentally the batch size should likely be
1000, not 100, maybe even configurable).
