> We need to crystallize the metastorage interface prototype from the IEP to understand how it will be integrated with other system components.
> Need to cover:
> * Asynchrony aspects
> * Possible error codes (connection failure -> unknown result vs Raft failure -> known result, etc)
> * Complex multi-updates (aka transactions)
> * Watchers. Each node can watch all updates and filter locally or adjust the watched ranges dynamically (consistency is important here)
> These interfaces are considered "client" interfaces as they will be available on all nodes in the cluster
