>
> 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.
