We don't want to keep another (known) bug lingering around in Flink 1.18. I upgraded the dependency to 6.9.0 and will do a pass through the diff between v6.6.2 and v6.9.0 to check whether there's something else we have to keep in mind. :thinking: -- This is an automated message from the Apache Git Service.
