The test that gotten slow; how many test cases does it actually contain
/ how many jobs does it actually run?
Are these tests using the table/sql API?

We are also observing extreme slow down (5+ minutes vs 15 seconds) in
1 of 2 integration tests . Both tests use Kafka. The slow test
uses org.apache.flink.runtime.minicluster.TestingMiniCluster, this
test tests complete job, which consumes and produces Kafka messages.
Not affected test extends org.apache.flink.test.util.AbstractTestBase
which uses MiniClusterWithClientResource, this test is simpler
and only produce Kafka messages.
Thanks,
Alexey

Hi David,
I guess, you're referring to [1]. But as Chesnay already pointed out
in the previous thread: It would be helpful to get more insights into
what exactly your tests are executing (logs, code, ...). That would
help identifying the cause.

Hi,
we were going to upgrade our application from Flink 1.14.4 to
Flink 1.15.2, when we noticed, that all our job tests, using a
MiniClusterWithClientResource, are multiple times slower in 1.15
than before in 1.14. I, unfortunately, have not found mentions in
that regard in the changelog or documentation. The slowdown is
rather extreme I hope to find a solution to this. I saw it
mentioned once in the mailing list, but there was no (public)
outcome to it.
I would appreciate any help on this. Thank you in advance.
Best
David
