>                 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
