If we agree on the repeated instantiation of ExecutableStage, then I can take this up in a separate PR (for both, batch and streaming translation). I would do that once we have test and end-to-end coverage, right now the translators are still not wired. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
