[jira] [Created] (DRILL-5) Create trivial interpreter for a logical plan

Ted Dunning created DRILL-5:
-------------------------------

             Summary: Create trivial interpreter for a logical plan
                 Key: DRILL-5
                 URL: https://issues.apache.org/jira/browse/DRILL-5
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Ted Dunning


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.

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.
