Subject [jira] [Updated] (TAJO-494) Extend TajoClient to run a query with a plan context serialized as the JSON form
Date Wed, 02 Apr 2014 05:06:15 GMT

     [ https://issues.apache.org/jira/browse/TAJO-494?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.)
