## What is the purpose of the change This PR proposes to discard watermarks when feed a datastream into iteration body since watermarks are not correctly processed in iteration module. To avoid the possible bugs, we plan to add a java doc to explain that `flink-m-iteration` module cannot deal with watermarks for now. We also leave it as a TODO here and plan to support it in the future. ## Brief change log - Adds a java doc to explain that iterations cannot deal with watermarks correctly. - Removed watermarks for all datastreams that are fed into a iteration body. ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (no) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (no) ## Documentation - Does this pull request introduce a new feature?
