This isn't a typical use case. FWIW, a decade ago, we used sqlite as the persistence mechanism for an in-memory KV store called membase. (See https://github.com/membase/ep-engine https://github.com/membase/ep-engine). This was powering 50M+ DAU traffic in production for very intense write-heavy traffic. It did its job well. Around that time we also considered leveldb (and rocksdb a bit later) as alternative to sqlite.
