Hi all, Using TLS1.3 (with JDK11) is causing an intermittent increase in inter-broker p99 latency, as mentioned by Yiming in Kafka-9320<https://issues.apache.org/jira/browse/KAFKA-9320?focusedCommentId=17401818&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-17401818>. We tested this with Kafka 2.8. The issue seems to be because of a renegotiation exception being thrown by
read(ByteBuffer dst) & write(ByteBuffer src) in clients/src/main/java/org/apache/kafka/common/network/SslTransportLayer.java This exception is causing the connection to close between the brokers before read/write is completed. In our internal experiments we have seen the p99 latency stabilize when we remove this exception. Given that TLS1.3 does not support renegotiation, can I make it applicable just for TLS1.2? I have also created a ticket<https://issues.apache.org/jira/browse/KAFKA-13418> Any feedback is welcome. Thank you, Shylaja
