Gabor Gevay created FLINK-4575: ---------------------------------- Summary: DataSet aggregate methods should support POJOs Key: FLINK-4575 URL: https://issues.apache.org/jira/browse/FLINK-4575 Project: Flink Issue Type: Improvement Components: DataSet API Reporter: Gabor Gevay Priority: Minor
The aggregate methods of DataSets (aggregate, sum, min, max) currently only support Tuples, with the fields specified by indices. With https://issues.apache.org/jira/browse/FLINK-3702 resolved, adding support for POJOs and field expressions would be easy: {{AggregateOperator}} would create {{FieldAccessors}} instead of just storing field positions, and {{AggregateOperator.AggregatingUdf}} would use these {{FieldAccessors}} instead of the Tuple field access methods. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
