python-lmdb

This is a universal Python binding for the LMDB 'Lightning' Database.
LMDB is a tiny database with the following properties:

Ordered map interface (keys are always lexicographically sorted).
Reader/writer transactions: readers don’t block writers,
writers don’t block readers.
Each environment supports one concurrent write transaction.
Cheap read transactions.
Environments may be opened by multiple processes on the same host.
Multiple named databases may be created with transactions covering
all named databases.
Memory mapped, allowing for zero copy lookup and iteration.
This is optionally exposed to Python using the buffer() interface.
Maintenance requires no external process or background threads.
No application-level caching is required:
LMDB uses the operating system’s buffer cache.
