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.
