ATTACHMENT ID: 12947348 - 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
>
>
> 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.
