[jira] [Created] (DRILL-3387) Push down joins into source db
Magnus Pierre created DRILL-3387:
------------------------------------
Summary: Push down joins into source db
Key: DRILL-3387
URL: https://issues.apache.org/jira/browse/DRILL-3387
Project: Apache Drill
Issue Type: Sub-task
Components: Storage - Other
Affects Versions: 1.0.0
Reporter: Magnus Pierre
Assignee: Jacques Nadeau
The current implementation of the JDBC plugin to connect to source databases does not push down joins. In order for this to happen, we need to implement a StoragePluginOptimizerRule that converts the physical plan to source side joins.
Furthermore, the scan spec and the reader need to be extended in order to implement the push down.
