Resolution: Fixed
> Deal with the interface between push and pull modes in exchange operators

> Key: DRILL-135
> URL: https://issues.apache.org/jira/browse/DRILL-135
> Project: Apache Drill
> Issue Type: Bug
> Reporter: Ted Dunning
>
> The issue is that naive buffering will result in an execution thread reading
> data for a while and then munching on data for a while. The reading is pull
> oriented while the execution is push.
> With better buffering and scheduling, the worker could overlap reading and
> processing. That is the goal of this JIRA.
