EJDB is an embedded JSON database engine. It aims to be a fast MongoDB-like NoSQL library that can be embedded into C/C++/Nodejs/Python3/Lua applications. It features collection-level write locking, collection level transactions, string token matching queries, and a Node.js binding.
TomP2P is a P2P-based high performance key-value pair storage library. Each peer has a table (either disk-based or memory-based) to store its values. A single value can be queried or updated with a secondary key. The underlying communication framework uses Java NIO to handle many concurrent connections.
TSM monitor is a Web application written in PHP to help TSM administrators quickly get reports and health status information from their TSM servers. It generates its content dynamically so one can easily add or modify queries to adapt the application to one’s own needs. It features customizable queries, a dynamically generated navigation menu, an overview page with traffic light logic, graphical timetable charts for queries with start and end time (like backups and schedules), multiple servers, login protection (authentication against a default TSM server), and result caching for better performance.
xNBD is yet another NBD (Network Block Device) server program, which is fully compatible with the NBD client driver in the Linux kernel. In comparison with the original NBD server, it provides possibly better I/O performance by using mmap(), concurrent access from multiple clients, distributed Copy-on-Write disk, and live storage migration for virtual machines.
Memventi is a Venti daemon. It speaks the same Venti protocol as the real Venti in Plan 9 from Bell Labs. It is a storage server that stores data blocks up to 56KB using its SHA-1 hash (called its score) to address it. It keeps a mapping of score to disk location in memory (in a memory-efficient manner). Blocks written cannot be removed, and blocks are only written once. Memventi writes new blocks to an append-only file, thereby making file corruption due to bugs practically impossible.
Sirix is a versioned tree-based storage system. It provides Snapshot Isolation through MVCC and is best suited for flash-based storage. The tree encoding is suited for heavy update operations. It provides diffing algorithms either to import diffs between currently shredded (imported) XML documents to update a tree structure or to get the differences between versions of a tree structure. A GUI provides several visualizations for comparing imported tree structures.
piler is an email archiving application with all the features required for an average company. The most prominent features are full text searching, deduplication, compression, encryption, digital fingerprinting, policy rules, access control, a built-in SMTP server, and Active Directory/openldap support.
