David Mao created KAFKA-18167: --------------------------------- Summary: Disable JDK session ticket extension by default Key: KAFKA-18167 URL: https://issues.apache.org/jira/browse/KAFKA-18167 Project: Kafka Issue Type: Task Reporter: David Mao Assignee: David Mao
JDK 14 enabled the TLS session ticket extension by default. This can cause severe cpu regression with certain JDK distributions, see: https://bugs.openjdk.org/browse/JDK-8298381 and adds some non-trivial CPU overhead to TLS handshaking in other cases. Since JDK 17 is now the minimum JDK version for broker deployments, we should consider disabling TLS session tickets by default. This minimizes upgrade friction for customers who may not be aware of these issues. -- This message was sent by Atlassian Jira (v8.20.10#820010)
