      eos-dom-akka is not panning out due to multiple reasons:

      • poor transition performance: chasing-the-leader CSIT has noticeable performance drop
      • Akka itself has changed licensing and we want to move away

      We used to have an implementation based on sal-distrubuted-datastore, which, at the end of the day, is the wrong layer to integrate on.

      Create eos-dom-akka-raft, which will provide eos-dom-api based on sal-akka-raft, replicating the appropriate state information.

      The new component needs to have two aspects:

      • EosRaftActor, which runs on every one and dynamically forms a cluster
      • implementation of DOMEntityOwnershipService hosted by the EosRaftActor

      What we want to achieve is an omni-present, majority-election-constrolled (hence sal-akka-raft), DOMEntityOwnershipService.

      The implementation is split in the middle:

      • registration of candidates pushes info to master
      • activation of candidates is replicated from master
