I am not familiar with SplinterDB, but I do have a lot of familiarity with RocksDB. These types of k/v storage layers are designed to handle hundreds of thousands of not millions of operations per sec. Especially the way they handle writes (typically with an LSM) is very different from SQLite, and it shows in terms of throughput of e.g. random writes.

I'd say that these low-level storage engines have more in common with filesystems than SQLite, they're just not in the same ballpark at all.
