Description
In Hazelcast 5.5+, the CP subsystem is removed from the community edition, and is only available in the enterprise edition.
It appears like if we move to hazelcast 5.5+, the hazelcast-atomicvalue (atomicnumber) component either needs to be removed or the data structure backing it needs to change - the IAtomicLong it uses is a CP subsystem only feature https://docs.hazelcast.com/hazelcast/5.6/data-structures/iatomiclong . We can replace most of the functionality with a PNCounter https://docs.hazelcast.com/hazelcast/5.6/data-structures/pn-counter with one limitation - PNCounter does not offer a compare/compareAndSet method. I think offering a new component here (hazelcast-pncounter) seems like a better approach because it is more descriptive of the underlying data structure used and because we would be removing significant functionality because no compareAndSet is available.
We should deprecate hazelcast-atomicvalue (atomicnumber) in 4.19.0 and create a hazelcast-pncounter to replace it. We can then safely remove hazelcast-atomicvalue in a future release and safely upgrade to hazelcast 5.5.0 or 5.6.0.
