> It is very common that there are many repeated values in the result set of a
> query, especially when JOINs are present in the 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.
