[GitHub] [kafka] ableegoldman opened a new pull request #10187: MINOR: document restriction against running multiple Streams apps on same state.dir
ableegoldman opened a new pull request #10187:
URL: https://github.com/apache/kafka/pull/10187
Running more than one Streams instance on the same physical state directory has never been supported, but until now it's also not really been enforced. Since we fixed Streams to fail fast in the case of this misconfiguration instead of offering vague symptoms, we will throw an exception on startup if it is detected. We should document this clearly as some users may have been using this setup for testing (note: there's no reason to do this in a real production app, as you should either scale up by adding more threads and/or scale out by adding new instances with their own storage)
