ATTACHMENT ID: 12954529 - PreCommit-HIVE-Build > ACID: Allow DbTxnManager to ignore non-ACID table locking > --------------------------------------------------------- > > Key: HIVE-20801 > URL: https://issues.apache.org/jira/browse/HIVE-20801 > Project: Hive > Issue Type: Bug > Components: Locking, Transactions > Affects Versions: 4.0.0 > Reporter: Gopal V > Assignee: Gopal V > Priority: Major > Labels: Branch3Candidate, TODOC > Attachments: HIVE-20801.1.patch, HIVE-20801.2.patch, > HIVE-20801.2.patch, HIVE-20801.3.patch > > > Enabling ACIDv1 on a cluster produces a central locking bottleneck for all > table types, which is not always the intention. > The Hive locking for non-acid tables are advisory (i.e a client can > write/read without locking), which means that the implementation does not > offer strong consistency despite the lock manager consuming resources > centrally. > Disabling this lock acquisition would improve the performance of non-ACID > tables co-existing with a globally configured DbTxnManager implementation. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
