[jira] [Created] (KAFKA-13734) Selector can make use of JDK 11 zero copy NIO select

Francesco Nigro created KAFKA-13734:
---------------------------------------

             Summary: Selector can make use of JDK 11 zero copy NIO select
                 Key: KAFKA-13734
                 URL: https://issues.apache.org/jira/browse/KAFKA-13734
             Project: Kafka
          Issue Type: Improvement
          Components: clients, producer 
            Reporter: Francesco Nigro


JDK 11 has introduced zero copy select ie [https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/nio/channels/Selector.html#select(java.util.function.Consumer)] that can be used to reduce the amount of GC created by Selector::poll.

It would be nice to access these new methods without impacting on existing JDK (< 11): MethodHandler::invokeExact seems a good candidate to do it.
