> Hi all,
> In ReplicationControlManager there is a max of 10,000 partitions allowed in a
> single create topics request. See
> [here|https://github.com/apache/kafka/blob/trunk/metadata/src/main/java/org/apache/kafka/controller/ReplicationControlManager.java#L152].
> In an app I am seeing this limit being hit. I am trying to reproduce the
> error in an integration test, but by creating so many partitions the test is
> becoming slow and flaky.
> I am hoping to make this value configurable on the controller side. Of course
> it will default to 10,000. By making the value configurable users can set the
> value to a lower one in tests.
