----------------------------------------
Summary: Partial aggregation for collect_set / collect_list
Key: SPARK-18932
URL: https://issues.apache.org/jira/browse/SPARK-18932
Project: Spark
Issue Type: Improvement
Components: SQL, Structured Streaming
Reporter: Michael Armbrust
The lack of partial aggregation here is blocking us from using these in
streaming. It still won't be fast, but it would be nice to at least be able to
use them.
