             Summary: Promotion of vectors from standard to embedded vectors
                 Key: DRILL-1262
                 URL: https://issues.apache.org/jira/browse/DRILL-1262
             Project: Apache Drill
          Issue Type: Sub-task
            Reporter: Jason Altekruse


For cases where the schema changes frequently, such as in the json reader, we will want to allow the operators to assume regular vectors can be used until we hit a schema change, at which time the vector should be promoted to an Embedded Vector. This should be applied after checking to see if the types are compatible for implicit casting, to avoid full promotion to an Embedded vector if it is not necessary.
