It’s going to have much lower write throughput, since SQLite is single-writer and on top of that you need to do Raft consensus. TiDB and CockroachDB can handle concurrent writes easily. Cockroach runs raft per “range” of 128mb of the key space, I’m not as familiar with TiDB. Vitess is an orchestration layer over MySQL, and MySQL handles concurrent writes easily.
