-------------------------------------
Summary: Allow parallel computation of metadata aggregating
Key: DRILL-7433
URL: https://issues.apache.org/jira/browse/DRILL-7433
Project: Apache Drill
Issue Type: Sub-task
Affects Versions: 1.17.0
Reporter: Vova Vysotskyi
Assignee: Vova Vysotskyi
In the scope of DRILL-7273 was implemented metadata collecting, but every
aggregation is created using SINGLE distribution traits, and therefore metadata
for every level is calculated using a single aggregate operator.
The aim of this Jira is to allow creating several aggregate operators for the
same metadata level to make metadata calculations more scalable.
