Jihoon Son updated TAJO-494:
----------------------------
Description: In some OLAP applications which has a separate query engine
such as Tajo, they accept SQL-like languages and parse them to generate query
plans. Mondrian is a representative example of these applications. If
TajoClient accepts query plans of the JSON form, user queries can be
efficiently executed without the duplicated parse phase. (was: The current
client only supports sql strings. This obstructs that other systems run queries
on Tajo via other query languages.
This issue extends the TajoClient to accept a plan context to run queries. So,
those systems can parse and generate a plan for a given query, and execute it
on Tajo.)
> Extend TajoClient to run a query with a plan context serialized as the JSON
> form
