> String Caching For Rows

> Key: HIVE-16663
> URL: https://issues.apache.org/jira/browse/HIVE-16663
> Project: Hive
> Issue Type: Improvement
> Components: Beeline
> Affects Versions: 2.0.1
> Reporter: BELUGA BEHR
> Priority: Minor
> Attachments: HIVE-16663.1.patch, HIVE-16663.2.patch,

>
> It is very common that there are many repeated values in the result set of a
> query. As it currently stands, beeline does not attempt to cache any of
> these values and therefore it consumes a lot of memory.
> Adding a string cache may save a lot of memory. There are organizations that
> use beeline to perform ETL processing of result sets into CSV. This will
> better support those organizations.
