-------------------------------------

             Summary: In all non-root fragments, Drill recreates storage plugin instances for every minor fragment
                 Key: DRILL-4000
                 URL: https://issues.apache.org/jira/browse/DRILL-4000
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Jacques Nadeau
            Assignee: Jacques Nadeau
             Fix For: 1.3.0


Drill is creating ephemeral storage plugin instances when a plan is deserialized. As such, every minor fragment of a query has Drill create a separate storage plugin instance. Depending on the cost of storage plugin creation, this could be quite expensive.
