Summary: Streaming aggregations on array types
Key: FLINK-1188
URL: https://issues.apache.org/jira/browse/FLINK-1188
Project: Flink
Issue Type: Improvement
Components: Streaming
Affects Versions: 0.8-incubating
Reporter: Márton Balassi
Assignee: Gyula Fora
Currently aggregations work on fields of tuples, the goal of the issue is to
extend this functionality to positions of arrays. One solution is to use an
implementation of the KeySelector interface, however it would be a nice
enhancement to have an API option for arrays, e.g. DataStream<int[]>
intSream.min(0).
