> Affects Versions: 0.10.2

> The implicit conversion from {{Seq}} to Flink DataStream needs to create internally a new execution environment.
> This method is confusing to use. If one uses the Seq in a program that uses a different execution environment, then different streams run on different execution environments.
> The overhead of manually calling {{env.fromElements(seq)}} is quite low.
