Resolution: Fixed
> Pass down projections into storage engines
> ------------------------------------------
>
> Key: DRILL-279
> URL: https://issues.apache.org/jira/browse/DRILL-279
> Project: Apache Drill
> Issue Type: New Feature
> Environment: Currently projections is not passed down to storage
> engines, therefore we are inputing all data from the data source where it is
> unnecessary.
> Passing down projections can allow the storage engine to only select the
> fields necessary and potentially reduce each batch size
