Content-Type: text/plain Message-Id: <20150702082416.C41D8E02A2@git1-us-west.apache.org> Date: Thu, 2 Jul 2015 08:24:16 +0000 (UTC) Github user gyfora commented on the pull request: https://github.com/apache/flink/pull/879#issuecomment-117955131 This is a very massive PR, the changes seem very reasonable. I wonder why do we have a ~10% slowdown with 500ms watermarks? It seems to be lightweight, but this is a quite significant performance hit I would not expect. --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.
