> ORC: Cleanup writer per-row synchronization
> -------------------------------------------
>
> Key: HIVE-10191
> URL: https://issues.apache.org/jira/browse/HIVE-10191
> Project: Hive
> Issue Type: Bug
> Components: File Formats
> Affects Versions: 1.2.0
> Reporter: Gopal V
> Assignee: Gopal V
> Attachments: HIVE-10191.1.patch, HIVE-10191.2.patch,

>
> ORC writers were originally meant to be thread-safe, but in the present day
> implementation each ORC writer is entirely share-nothing which converts most
> of the synchronized blocks in ORC as entirely uncontested locks.
> These uncontested locks prevent the JVM from inlining/optimizing these
> methods, while adding no extra thread-safety to the ORC writers.
