> 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.
