What does it mean when Lettuce Core logs indicate missing epoll and kqueue libraries during initialization?

Question

I am using the Lettuce Core library, a Java Redis SDK, and noticed the following logs during the client initialization:

Dec 05, 2023 3:48:47 PM io.lettuce.core.EpollProvider <clinit>
INFO: Starting without optional epoll library
Dec 05, 2023 3:48:47 PM io.lettuce.core.KqueueProvider <clinit>
INFO: Starting without optional kqueue library

What's the significance of these logs, and should I be concerned about not having the optional epoll and kqueue libraries? I'm particularly interested in understanding any performance considerations or functional differences when these optional libraries are not included.
