    [ https://issues.apache.org/jira/browse/DRILL-5?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13477546#comment-13477546 ] 

Ted Dunning commented on DRILL-5:
---------------------------------

OK.  Checked in a version that is on the edge of working for simple queries.

I will be refining this and adding tests over the next few days.

> 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.
