             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.
