LexisNexis Open-Sources its Hadoop Alternative

A month ago, I wrote about alternatives to the Hadoop MapReduce platform and HPCC was included in that article. For more information, see here.

LexisNexis has open-sourced its alternative to Hadoop, called High Performance Computing Cluster. The code is available on GitHub. For years the code was restricted to LexisNexis Risk Solutions. The system contains two major components:

Thor (Thor Data Refinery Cluster) is the data processing framework. It “crunches, analyzes and indexes huge amounts of data a la Hadoop.”
Roxie (Roxy Radid Data Delivery Cluster) is more like a data warehouse and is designed with quick querying in mind for frontends.

The protocol that drives the whole process is the Enterprise Control Language which is said to be faster and more efficient than Hadoop’s version of MapReduce. A picture is a much better way to show how the system works. Below is a diagram from the Gigaom article from which most of this information originates.

To me, Roxie seems much more exciting because it seems to complement (or replace) several technologies currently in the space. I do not know all the details, but it seems to potentially encapsulate technologies such as HBase, Hive, RabbitMQ and MemcacheDB, technologies that are common used to query and [...]
