Hi Greg I know JDK 8 will solve the problem certainly, but I wondering if JDK8 has been deprecated after Kafka 3? Can I use JDK 8 with Kafka 3.2.1? Thank you. On 2023/05/22 20:55:01 Greg Harris wrote: > Vic, > > While you can certainly try that, I don't know if that will solve the problem. >

Re: Re: Kafka 3.2.1 performance issue with JDK 11
