Subject [jira] [Created] (DRILL-5168) No direct Streaming Agg test cases
Date Thu, 29 Dec 2016 02:54:58 GMT
Paul Rogers created DRILL-5168:

             Summary: No direct Streaming Agg test cases
                 Key: DRILL-5168
                 URL: https://issues.apache.org/jira/browse/DRILL-5168
             Project: Apache Drill
          Issue Type: Bug
    Affects Versions: 1.8.0
            Reporter: Paul Rogers
            Priority: Minor

Drill's provides both hash and streaming aggregate operators. Both reside in the {{org.apache.drill.exec.physical.impl.aggregate}}
package. The corresponding test package contains tests only for the hash aggregate: {{TestHashAggr}}.
No corresponding unit tests exists for streaming aggregates.

It may be that other, SQL-level tests have the effect of testing streaming aggregates (but
I've not yet found such tests.) Without unit tests, we cannot guarantee that changes to streaming
aggregates will work correctly.
