> Project: Flink
> Issue Type: Improvement
> Components: API / DataStream
> Affects Versions: 1.8.0

> Priority: Major
> Fix For: 1.10.0

>
> We've already have fromElements function in StreamExecutionEnvironment to
> generate a non-parallel DataStreamSource. We should introduce a similar
> fromParallelElements function because:
> 1. The current implementations of ParallelSourceFunction are mostly bound to
> external resources like kafka source. And we need a more lightweight parallel
> source function that can be easily created. The SplittableIterator is too
> heavy by the way.
> 2. It's very useful if we want to verify or test something in a parallel
> processing environment.
