Hi @andybets - thanks for your question. Currently a node with only account history uses 204GB for the state file while a node with everything except for account history uses 190GB. Today, Jussi (api.steemit.com) is being used to split requests to the different clusters of nodes if they are not already cached. In the future, many of these requests will be split off to SBDS (for account history) and Hivemind (for tags/follows). RocksDB for account history (and later probably tags/follows) will be an alternate option. Either configuration can be forwarded through Jussi without the frontend (Condenser) needing to be aware of the change.
