-------------------------------
Summary: Change the de/serialization protocol of LogicalPlan of
QueryUnitAttempt from Json to ProtocolBuffer
Key: TAJO-269
URL: https://issues.apache.org/jira/browse/TAJO-269
Project: Tajo
Issue Type: Task
Components: master, worker
Reporter: Jihoon Son
Assignee: Jihoon Son
Fix For: 0.3-incubating
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 it's overhead is quite small and
already used in other modules of Tajo.
