> At this moment, every raft group creates RocksDBLogStorage which, in turn, creates an instance of RocksDB without sharing resources with other log storages. This inflicts memory overhead and leads to out of memory killer killing process on TeamCity.
> We need to use one rocksdb instance for all log storages
