levelup: prior art?

[bryanburgers]

Does https://github.com/Level/levelup provide any prior art that can be used? It's a binary object store that uses keys and values, and has a lot of backends implemented (which problem means it generically solves many problems – it's not just for Google's leveldb).

(I'm not offended if it doesn't. I just came across your tweet about this repo and was curious if levelup could provide some use cases, etc.)

The successor to levelDB for block store style access is probably the random-access-* family of modules such as https://github.com/mafintosh/random-access-file. It might prove to be valuable prior art, as it's a good example of what people that need block store APIs actually use in the wild to implement databases on.

And it's also important to note that random-access modules only implement read() and write(). It may make sense to implement an asynchronous size() or length(), but this can also be done in userland by writing a first block of metadata, so these aren't strictly necessary. Everything else can be built on top of asynchronous read() and write().
