Subject [jira] [Created] (DRILL-3500) Provide additional information while registering storage plugin optimizer rules
Date Wed, 15 Jul 2015 21:05:04 GMT
Mehant Baid created DRILL-3500:
----------------------------------

             Summary: Provide additional information while registering storage plugin optimizer
rules
                 Key: DRILL-3500
                 URL: https://issues.apache.org/jira/browse/DRILL-3500
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Mehant Baid
            Assignee: Mehant Baid
             Fix For: 1.2.0


Currently all the optimizer rules internal to Drill have access to QueryContext. This is used
by a few rules like PruneScanRule which invoke the interpreter to perform partition pruning.
However the rules that belong to specific storage plugins don't have access to this information.
This JIRA aims to do the following

1. Add a new interface OptimizerRulesContext that will be implemented by QueryContext. It
will contain all the information needed by the rules. This context will be passed to the storage
plugin method while getting the optimizer rules specific to that storage plugin.

2. Restrict existing internal rules to only accept OptimizerRulesContext instead of QueryContext
so information in QueryContext has better encapsulation.
