------------------------------------------------
Summary: Druid adapter: topN returns approximate results
Key: CALCITE-1587
URL: https://issues.apache.org/jira/browse/CALCITE-1587
Project: Calcite
Issue Type: Bug
Components: druid
Affects Versions: 1.11.0
Reporter: Jesus Camacho Rodriguez
Assignee: Julian Hyde
Fix For: 1.12.0
Currently, we convert to _topN_ queries. However, metrics returned by Druid
will be approximate values. Thus, probably we should not convert to Druid topN
queries and rather always use Druid groupBy.
