PoAn Yang commented on KAFKA-18797:
-----------------------------------
I found that testLargeAssignmentAndGroupWithUniformSubscription uses around 2G
memory, because it creates 1 million partitions. The maximum heap size for
flaky test is 3G and run test parallelly. It may have chance to get OOM. Since
the test case doesn't really do assertion, we can probably rewrite it as a jmh
case.
