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.

BlackRay Data Engine

BlackRay is a relational database system designed to offer performance features commonly associated with search engines. It offers SQL support and sophisticated operational and management features. Load-balancing and operational stability by means of N+1 redundance are included. BlackRay is ... [More] called a "Data Engine" since it combines traditional, relational database features and SQL with the power and flexibility of search engines. It is a true hybrid, offering transaction support, data-versioned snapshots, and sophisticated function-based indices. Wildcards, phonetic, and fuzzy logic searches are supported, as well. Commercial support is available, and the project is released under a the GPLv2 license. [Less]
