Lefty Leverenz commented on HIVE-7366:
--------------------------------------
Any doc needed, or is this strictly behind-the-scenes?
By the way, the wiki only mentions direct SQL in three parameter descriptions:
* [Configuration Properties -- hive.metastore.integral.jdo.pushdown |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.metastore.integral.jdo.pushdown]
* [Configuration Properties -- hive.metastore.try.direct.sql |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.metastore.try.direct.sql]
* [Configuration Properties -- hive.metastore.try.direct.sql.ddl |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.metastore.try.direct.sql.ddl]
> getDatabase using direct sql

> Key: HIVE-7366
> URL: https://issues.apache.org/jira/browse/HIVE-7366
> Project: Hive
> Issue Type: Bug
> Components: Metastore
> Affects Versions: 0.14.0
> Reporter: Sushanth Sowmyan
> Assignee: Sushanth Sowmyan
> Priority: Critical
> Fix For: 0.14.0

> Attachments: HIVE-7366.2.patch, HIVE-7366.3.patch, HIVE-7366.4.patch,

>
> Given that get_database is easily one of the most frequent calls made on the
> metastore, we should have the ability to bypass datanucleus for that, and use
> direct SQL instead.
> This was something that I did initially as part of debugging HIVE-7368, but I
> think that given the frequency of this call, it's useful to have it in
> mainline direct sql.
