> ---------------------------------------------
>                 Key: DRILL-5
>                 URL: https://issues.apache.org/jira/browse/DRILL-5
>             Project: Apache Drill
>          Issue Type: Bug
>            Reporter: Ted Dunning
>            Assignee: Jacques Nadeau
> Using the output of the SSA parser for a logical plan, it should be possible to build
an unoptimized, terribly slow reference interpreter that does drill-like things to JSON data.
> The input would be a plan in the form of a DAG which references a JSON data file on disk.
 Evaluation of the DAG would result in a stream of trees which could be stored back to disk
for inspection or compared to reference values for testing.
