https://github.com/oracle/coherence is now open source. I'm not aware of their licence but a cluster implementation using it seems to be very interesting.
I know Vert.x 4 redesigned clustering SPI. I will study how to implement it but anyway I'd like to give this suggestion.
thanks @rodolfodpk that's an option we were unaware of. We will let community step up with a Coherence implementation for Vert.x cluster manager and help them implement it.
