> Key: TAJO-269
> URL: https://issues.apache.org/jira/browse/TAJO-269
> Project: Tajo
> Issue Type: Improvement
> Components: query master, worker

>
> 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.
