This module allows OpenResty applications to use the LMDB (Lightning Memory-Mapped Database) inside the Nginx worker process. It has two parts, a core module built into Nginx that controls the life cycle of the database environment, and a FFI based Lua binding for interacting with the module to access/change data.
