Eugene Koifman commented on HIVE-17710: --------------------------------------- Also consider closing an implicit txn immediately after compiling if we know it only uses External tables. Somewhat orthogonal, maybe useful to have ReadOnly txn mode - this could simplify TxnHandler.commitTxn() > LockManager and External tables > ------------------------------- > > Key: HIVE-17710 > URL: https://issues.apache.org/jira/browse/HIVE-17710 > Project: Hive > Issue Type: New Feature > Components: Transactions > Reporter: Eugene Koifman > Assignee: Eugene Koifman > > should the LM take locks on External tables? Out of the box Acid LM is being > conservative which can cause throughput issues. > A better strategy may be to exclude External tables but enable explicit "lock > table/partition <lock mode>" command (only on external tables?). -- This message was sent by Atlassian JIRA (v6.4.14#64029)
