Hi, I'm working together with Richard Deurwaarder on the PubSub Source and Sink https://issues.apache.org/jira/browse/FLINK-9311
We currently have most of the code done and we also have several tests that verify the behavior by actually reading and writing messages to and from PubSub. These tests use a docker image provided by Google that includes the pubsub emulator. Starting and stopping this thing is really fast. Starting up, creating topic, running a few tests and cleaning up takes about 5 seconds. Although the complete set of tests run on my machine in about 20-25 seconds it does mean that anyone doing that MUST have docker installed locally. So my question to the committers: Do we simply leave these tests "always on" or do you want them to be "off by default" or something else. I case you do not want the "always on" then please indicate how we should implement the "on"/"off" switch for these tests. Thanks. -- Best regards / Met vriendelijke groeten, Niels Basjes
