---------------------------------------
Summary: DataStream support for arrays as keys
Key: FLINK-5299
URL: https://issues.apache.org/jira/browse/FLINK-5299
Project: Flink
Issue Type: Improvement
Components: DataStream API
Affects Versions: 1.2.0
Reporter: Chesnay Schepler
It is currently not possible to use an array as a key in the DataStream api, as
it relies on hashcodes which aren't stable for arrays.
One way to implement this would be to check for the key type and inject a
KeySelector that calls "Arrays.hashcode(values)".
