Subject [jira] [Created] (DRILL-5) Create trivial interpreter for a logical plan
Date Sat, 13 Oct 2012 13:04:02 GMT
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.
