----------------------------------
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.
