Eugene Koifman updated HIVE-13795: ---------------------------------- Target Version/s: 1.3.0, 2.2.0 > TxnHandler should know if operation is using dynamic partitions > --------------------------------------------------------------- > > Key: HIVE-13795 > URL: https://issues.apache.org/jira/browse/HIVE-13795 > Project: Hive > Issue Type: Bug > Components: Transactions > Affects Versions: 1.3.0, 2.1.0 > Reporter: Eugene Koifman > Priority: Critical > > TxnHandler.checkLock() see more comments around > "isPartOfDynamicPartitionInsert". If TxnHandler knew whether it is being > called as part of an op running with dynamic partitions, it could be more > efficient. In that case we don't have to write to TXN_COMPONENTS at all > during lock acquisition. Conversely, if not running with DynPart then, we can > kill current txn on lock grant rather than wait until commit time. > if addDynamicPartitions() also knew about DynPart it could eliminate the > Delete from Txn_components... statement > This is an important perf optimization when it allows us to detect that > concurrent txns will have a WW conflict early -- This message was sent by Atlassian JIRA (v6.3.4#6332)
