somewhat unrelated, im very curious what insights you guys have regarding mmap'd db architectures. ive been exploring mdbx as a replacement for leveldb in core as sort of a moonshot side experiment, and mdbx (fork of lmdb) is essentially a mmap'd shadow paged btree. we saw some really promising benchmarks, but also a ton of write amplification. curious if you guys have any insights, since it seems you've rolled your own mmaped db architecture?

thanks, helpful insights. and not really a curiosity, more was looking into leveldb replacements for a different problem i want to solve. after experimenting with mdbx a bit, im arriving at some of the same conclusions re: mmap for general purpose database.
