Hyunsik Choi commented on TAJO-269:
-----------------------------------

+1

Actually, I've thought this way is better than the current implementation. However, I couldn't
start this work because this way requires a bunch of works.

> In the current implementation, the logical plan is serialized into a JSON object and
sent to each worker.
> However, the transmission of JSON object incurs the high overhead due to its large size.
> ProtocolBuffer is a good alternative because its overhead is quite small and already
used in other modules of Tajo.
