Yeah, I completely agree. Redis makes a great cache with richer operations, but less efficiency than memcached. Using it as a system of record in any context will come back to haunt you in the worst way. I first ran into the more minimal append only log persistence pattern with the jvm project Prevayler. It's not a totally unreasonable idea but has to be implemented carefully. The fork as copy on write mechanism initially seems clever, but in practice is extremely brittle. There's a reason classic databases have a lot of sophisticated logic around checkpointing and truncating the write ahead log. It's not a problem that can be oversimplified. I wouldn't be totally down on minimal btree implementations, but 1000 LOC is pushing it. Even LMDB as minimalist as it is, is around 10k as I recall.
