@kfaraz, some of the recently added embedded tests are failing, wondering if you have any thoughts. I’m pretty sure it’s not related to the change in this PR. I can also help take a look at some of these failures later when I get a chance

  🧪 - KafkaFaultToleranceTest | expected: <3000> but was: <3460>

Thanks for letting me know, @abhishekrb19 ! I have encountered some of these failures too. Will try to take a look.
