Assignee: Guozhang Wang
> Add implicit unlimited windowed aggregation for KStream
> -------------------------------------------------------
>
> Key: KAFKA-3192
> URL: https://issues.apache.org/jira/browse/KAFKA-3192
> Project: Kafka
> Issue Type: Sub-task
> Reporter: Guozhang Wang
> Assignee: Guozhang Wang
> Fix For: 0.10.0.0
>
>
> Some users would want to have a convenient way to specify "unlimited windowed
> aggregation" for KStreams. We can add that as a syntax-suger like the
> following:
> {code}
> KTable aggregateByKey(aggregator)
> {code}
> Where it computes the aggregate WITHOUT windowing, and the underlying
> implementation just use a RocksDBStore instead of a RocksDBWindowStore, and
> the returned type will be KTable, not KTable<Windowed, ?>.
> With this we can also remove UnlimitedWindows specs.
