How about using of Aeron?

[mijicd]

@plokhotnyuk While Aeron is amazing, I believe at first we'll lean toward using zio-nio. However, with proper wrapper, Aeron might be a nice alternative.

@plokhotnyuk as @mijicd mentioned we try to use as zio-nio for the time being. We are aware of Aeron, ZeroMQ, Chronicle and couple of others but mission of this library is not providing wrappers for other libraries which you can create yourself. This library is to provide performant building blocks that can be use to build distributed system from the ground.
