> Use DB auto-increment for indexes
> ---------------------------------
>
> Key: HIVE-18247
> URL: https://issues.apache.org/jira/browse/HIVE-18247
> Project: Hive
> Issue Type: Bug
> Components: Hive, Metastore
> Affects Versions: 3.0.0
> Reporter: Alexander Kolbasov
> Assignee: Alexander Kolbasov
> Priority: Major
> Labels: datanucleus, perfomance
> Attachments: HIVE-18247.02.patch
>
>
> I initially noticed this problem in Apache Sentry - see SENTRY-1960. Hive has
> the same issue. DataNucleus uses SEQUENCE table to allocate IDs which
> requires raw locks on multiple tables during transactions and this creates
> scalability problems.
> Instead DN should rely on DB auto-increment mechanisms which are much more
> scalable.
> See SENTRY-1960 for extra details.
