Projects

memcached

memcached is a high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.

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. [Less]

Redis

A persistent key-value database with built-in net interface written in ANSI-C for Posix systems.

Zope Object Database (ZODB)

The Zope Object Database provides an object-oriented database for Python that provides a high-degree of transparency. Applications can take advantage of object database features with few, if any, changes to application logic. ZODB includes features such as a plugable storage interface, rich transaction support, and undo.

PyTables

PyTables is a package for managing hierarchical datasets and designed to efficiently and easily cope with extremely large amounts of data. PyTables is built on top of the HDF5 library, using the Python language and the NumPy package (it also supports numarray and Numeric right out-of-the-box). It ... [More] features an object-oriented interface that, combined with C extensions for the peformance-critical parts of the code (generated using Pyrex), makes it a fast, yet extremely easy to use tool for interactively saving and retrieving very large amounts of data. One important feature of PyTables is that it optimizes memory and disk resources so that data takes much less space (specially if on-flight compression is used) than other solutions such as relational or object oriented databases.

Apache Xindice

claimed by Apache Software Foundation

Apache Xindice is a database designed from the ground up to store XML data or what is more commonly referred to as a native XML database.

Oracle Linux Cluster Filesystem (OLCF)

Oracle Cluster File System (OCFS) presents a consistent file system image across the servers in a cluster. OCFS allows administrators to take advantage of a files system for the Oracle database files (data files, control files, and archive logs) and configuration files. This eases administration of the Oracle Real Application Clusters.

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.

WKTRaster

Raster types for PostGIS. PostGIS WKT Raster is an ongoing project aiming at developing raster support in PostGIS. The goal of WKT Raster is to implement the RASTER type as much as possible like the GEOMETRY type is implemented in PostGIS and to offer a single set of overlay SQL functions ... [More] (like ST_Intersects) operating seamlessly on vector and raster coverages. [Less]

HiveDB

HiveDB is an open source framework for horizontally partitioning MySQL systems. HiveDB uses a partition-by-key scheme to manage sharded data stored in separate MySQL databases. Out of the box HiveDB supports simple JDBC or HIbernate via HIbernate Shards.
