Berkeley DB

Berkeley DB (BDB) is a high-performance, embedded database library with bindings in C, C++, Java, Perl, Python, Tcl, Smalltalk and many other programming languages. BDB stores arbitrary key/data pairs as byte arrays, and supports multiple data items for a single key. BDB can support thousands of ... [More] simultaneous threads of control or concurrent processes manipulating databases as large as 256 terabytes, on a wide variety of systems including most UNIX-like and Windows systems as well as real-time operating systems.

M2Collections

Modula-2 collections library. The library provides an API for collection ADTs, in particular: stacks, queues, double ended queues, priority queues, balanced binary search trees, patricia tries, dynamic arrays and hash tables to store arbitrary data. The hash table ADT allows data to be stored and ... [More] retrieved by reference or by copy, with built-in reference counting. All other ADTs allow data to be stored and retrieved by reference only. The library follows PIM4, it has no dependencies and it is platform independent. The library is tested with GM2 using option 'fpim4'. Under development. BSD style license. [Less]

leveldb

LevelDB is a library that implements a fast key-value store. Features * Keys and values are arbitrary byte arrays. * Data is stored sorted by key. * Callers can provide a custom comparison function to override the sort order. * The basic operations are Put(key,value) ... [More] , Get(key), Delete(key). * Multiple changes can be made in one atomic batch. * Users can create a transient snapshot to get a consistent view of data. * Forward and backward iteration is supported over the data. * Data is automatically compressed using the Snappy compression library. * External activity (file system operations etc.) is relayed through a virtual interface so users can customize the operating system interactions.

Tokyo Cabinet

Tokyo Cabinet is the successor of QDBM, a high performance database library similar to the DBM family. It also supports hash and B-tree databases and does not require any server process. The overall speed is improved compared to QDBM.

credis

Credis is a client library written in plain C for communicating with Redis servers. Redis is a high performance key-value database, refer to Redis project page for more information. Credis aims to be fast and minimalistic with respect to memory usage. It runs on Linux and should run on most posix ... [More] like systems, porting it to Windows or other platforms should be straightforward. WhyRedis seemed like what I was looking for in a social web project with high demands on scalability. Unfortunately a plain C client library was not available - until now. StatusCurrent status is pre-alpha. A simple credis test client is available but there are a few things to do before a proper release can be done. However, it should be good enough for development and test purposes. For source code examples and more information see credis project wiki. Feedback is highly appreciated. [Less]

Lightning Database

Lightning DB (aka MDB) is an ultra-high performance database using memory-mapped data. It is fully transactional with ACID guarantees and uses Multi-Version Concurrency Control and scales perfectly across large numbers of CPUs. It is also extremely compact, at only 35KB of object code for the ... [More] library. It is developed under the OpenLDAP Project but is also usable on its own. [Less]

Stash

Stash is a persistence engine for .NET. It eschews relational models and object/relational mapping and instead follows the No-Sql paradigm of storing serialised graphs or ‘documents’. It is effectively a Key/value store with access via Indexes. Stash currently uses BerkeleyDB as its ... [More] persistence store. Other persistent engines may be implemented. [Less]

KVSlib

C library for key-value storage. The library provides an API to create and use dynamic associative arrays for arbitrary data. Data may be stored and retrieved by copy or by reference. Stored data is reference counted to prevent dangling pointers. Optimised for fast lookups and large data sets. ... [More] Requires C99, no dependencies, platform independent. BSD style license. [Less]

HectorSharp

High level .NET Client for Cassandra

stuf

A collection of Python dictionaries supporting attribute-style access. Includes defaultdict, OrderedDict, restricted, and frozen implementations.
