MDBM C API.](https://github.com/yahoo/mdbm/) - MDBM is a super-fast memory-mapped key/value store. - MDBM is an ndbm work-alike hashed database library based on sdbm which is based on Per-Aake Larson’s Dynamic Hashing algorithms. - MDBM is a high-performance, memory-mapped hash database similar to the homegrown libhash. - The records stored in a mdbm database may have keys and values of arbitrary and variable lengths.
