Eugene Koifman created HIVE-17340: ------------------------------------- Summary: TxnHandler.checkLock(Connection dbConn, long extLockId) optimization Key: HIVE-17340 URL: https://issues.apache.org/jira/browse/HIVE-17340 Project: Hive Issue Type: Improvement Components: Transactions Reporter: Eugene Koifman Assignee: Eugene Koifman
This calls acquire(Connection dbConn, Statement stmt, long extLockId, LockInfo lockInfo) for each lock in the same DB transaction - 1 Update stmt per acquire(). There is no reason all of them cannot be sent in 1 statement if all the locks are granted With a lot of partitions this can be a perf issue -- This message was sent by Atlassian JIRA (v6.4.14#64029)
