> To preserve disk space Raft instance has to compact its log from time to time. Log compacting involves taking snapshot of all keys currently residing in memory and syncing them with persistent store.
> Storage should provide a generic API for that operation (which in fact is analogue of performing a checkpoint in Ignite 2.x) and RocksDB-based implementation.
