unrelated: I need a key-value storage engine/data structure that is suitable to use on a microcontroller, with sdcard as the storage medium. Performance isn't critical (within reason of course), but must need very little ram (10s-100s of bytes, at the high end), and of course must minimize/optimize sdcard writes and reads. Any suggestions?
ENOTENOUGHINFO: Any of the following changes what data structure should be used: read/write ratio, key size, data size, what is the interface to sdcard.
Gut feeling is that with TENS of bytes you will only get an append-only log.
