----------------------------------
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.
