Description

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.
