> Key: DRILL-26

> Project: Apache Drill
> Issue Type: New Feature
> Reporter: Timothy Chen

> Store (1 K)
> Store the stream output to a storage engine. The sink parameter references a
> defined datasource within the logical plan. The target parameter describes
> the storage engine specific parameters (e.g. storage type, filename, etc).
> The partition values describe how to partition the output data. Partitioning
> can be done on a random, hash or ordered basis. An optional start parameter
> describes the set of partitions to target. In the case that starts are not
> described, the system will determine an appropriate set of partitions based
> on the nature of the query and its execution plan. Since the Logical Plan
> is typically not a direct user interface, outputting to terminal is done
> through a special type of sink called an rpc sink. The consumer of the
> logical plan interface is then responsible for setting up an inbound rpc
> endpoint with which the execution layer can communicate the results.
