-------------------------------------
Summary: Allow sorting on aggregated streaming dataframe when the
output mode is Complete
Key: SPARK-15812
URL: https://issues.apache.org/jira/browse/SPARK-15812
Project: Spark
Issue Type: Sub-task
Reporter: Tathagata Das
Assignee: Tathagata Das
When the output mode is complete, then the output of a streaming aggregation
essentially will contain the complete aggregates every time. So this is not
different from a batch dataset within an incremental execution. Other
non-streaming operations should be supported on this dataset. In this JIRA, we
are just adding support for sorting, as it is a common useful functionality.
Support for other operations will come later.
