Subject [jira] [Comment Edited] (FLINK-1017) Add setParallelism() to Java API documentation

Well, I think both should be done (not necessarily by you).

For the first one, I would add it after "Project" but without a dedicated heading. Simply
state that for each transformation the parallelism and a name can be specified using the {{setParallelism()}}
and {{name()}} methods.

The "parallel execution" section, should describe how the parallelism execution of a program
can be specified. Since the parameters are already described at other places (system config,
environment, client, transformations), I would only describe how these settings relate to
each other (which overwrites which) and link to the appropriate locations in the documentation
for details.

> The Java API offers {{setParallelism()}} to control the degree of parallelism for each
operator. This feature is not documented and should be added.
