tcl-lmdb v0.3.5


tcl-lmdb - Tcl interface to the Lightning Memory-Mapped Database


This is the Lightning Memory-Mapped Database (LMDB) extension for Tcl using the Tcl Extension Architecture (TEA).

LMDB is a Btree-based database management library with an API similar to BerkeleyDB. The library is thread-aware and supports concurrent read/write access from multiple processes and threads. The DB structure is multi-versioned, and data pages use a copy-on-write strategy, which also provides resistance to corruption and eliminates the need for any recovery procedures. The database is exposed in a memory map, requiring no page cache layer of its own. This extension provides an easy to use interface for accessing LMDB database files from Tcl.
