Francesco Nigro updated KAFKA-13734:
------------------------------------
Description:
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 the currently
supported JDK version ie 8: MethodHandler::invokeExact seems a good candidate
to do it.
