WiredTiger is an extensible platform for data management. Its storage engine is optimized for high-throughput, big data applications. It can be configured for write-optimized (row-store) or read-optimized (column-store) access, as well as a hybrid of both. It separates the on-disk and in-memory representations of data, leading to a simpler, more compact file format and a large block I/O tailored for modern storage systems.
The Assimilation Monitoring Project is a highly scalable discovery-driven monitoring system. It integrates continuous discovery of servers, services, service dependencies, switch connections, and lots of other things into the monitoring process. The discovery is "stealthy" and will never set off any network security alarms. Adding servers doesn't measurably increase monitoring load, and the system is expected to easily scale into the 100K server range. The discovery work is distributed among all the nanoprobes (agents), which run scripts that spit out JSON. The central system (CMA) stores these strings and runs optional plugins to create graph nodes.
Shard-Query uses partitioning and sharding to add query parallelism and grid computing capabilities to MySQL. Multiple interfaces are included, from a commandline client to an object oriented interface to a MySQL proxy interface for nearly-completely transparent access to a sharded data set.
Java Gearman Service is a Java implementation of the gearman service, which provides a generic application framework that farms work out to other machines or processes that are better suited to do the work. It allows you to do work in parallel, to load balance processing, and to call functions in other languages. It can be used in a variety of applications, from high-availability Web sites to the transport of database replication events.
jFramework is a PHP framework that supports internationalization best practices, fast NIST 2 RBAC, optimized multi-database drivers, URL management, MVC best practices, certified security, incredible performance, full support for Web 2.0 including Comet, simple yet powerful templates, many plugins, an administration Web interface, options, a profiler and benchmarker, and much more.
tsx-tools provides headers and utilities for development with TSX (HLE/RTM) hardware transactional memory development on recent Intel CPUs. It includes compat headers that provide C inline functions support for RTM and HLE in various formats for older gcc compatible compilers (before gcc 4.8). These headers are useful to enable lock elision in a lock library or existing program. It also has various TSX related utilities, including a tool that detects the presence of TSX, a TSX aware assert, and various debugging utilities.
