-------------------------------------
Summary: 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
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
