Yongjin Choi commented on TAJO-1432:
------------------------------------
I implmented compressed result set as a session option.
To use this feature,
{code:sql}
set session "tajo.resultset.compress" to true;
{code}
or
{code:sql}
\set FETCH_COMPRESS true
{code}
Currently, only zlib compression codec is used (it's not difficult to add
another compression like snappy, etc.)
Any feedback is welcome.

> Project: Tajo
> Issue Type: Improvement
> Components: client
> Reporter: Yongjin Choi
> Assignee: Yongjin Choi
>
> Sometimes, Tajo should return big result set (a few or tens of gigabytes!)
> given a query.
> In many cases, the network bandwidth between client (BI tool) and tajo master
> is expensive or not good enough.
> So, it would be great if the communication between client and tajo master
> could be compressed as a session option.
