[jira] [Created] (DRILL-6829) Handle schema change in ExternalSort

Aman Sinha created DRILL-6829:
---------------------------------

             Summary: Handle schema change in ExternalSort
                 Key: DRILL-6829
                 URL: https://issues.apache.org/jira/browse/DRILL-6829
             Project: Apache Drill
          Issue Type: New Feature
            Reporter: Aman Sinha


While we continue to enhance the schema provision and metastore aspects in Drill, we also should explore what it means to be truly schema-less such that we can better handle \{semi, un}structured data, data sitting in DBs that store JSON documents (e.g Mongo, MapR-DB). 
 
The blocking operators are the main hurdles in this goal (other operators also need to be smarter about this but the problem is harder for the blocking operators).   This Jira is specifically about ExternalSort.
