[jira] [Created] (FLINK-11147) Add document for TableAggregate
Function
Hequn Cheng created FLINK-11147:
-----------------------------------
Summary: Add document for TableAggregate Function
Key: FLINK-11147
URL: https://issues.apache.org/jira/browse/FLINK-11147
Project: Flink
Issue Type: Sub-task
Components: Table API & SQL
Reporter: Hequn Cheng
Assignee: Hequn Cheng
Add document for {{TableAggregateFunction}}, similar to the document of {{AggregateFunction}}: https://ci.apache.org/projects/flink/flink-docs-release-1.7/dev/table/udfs.html#aggregation-functions
Most parts of {{TableAggregateFunction}} would be same with {{AggregateFunction}}, except for the ways of handling outputs. {{AggregateFunction}} outputs a scalar value, while {{TableAggregateFunction}} outputs a Table with multi rows and columns.
