> Procedure v2 (aka Notification Bus) aims to provide a unified way to build:
> * multi-steps procedure with a rollback/rollforward ability in case of failure (e.g.
create/delete table)
> ** HBASE-12070
> * notifications across multiple machines (e.g. ACLs/Labels/Quotas cache updates)
> ** Make sure that every machine has the grant/revoke/label
> ** Enforce "space limit" quota across the namespace
> ** HBASE-10295 eliminate permanent replication zk node
> * procedures across multiple machines (e.g. Snapshots)
> * coordinated long-running procedures (e.g. compactions, splits, ...)
> * Synchronous calls, with the ability to see the state/result in case of failure.
> ** HBASE-11608 sync split
> still work in progress/initial prototype: https://reviews.apache.org/r/27703/
