To make it easier for people to contribute to Virgil, we've moved the project to github!

As a side note...

I've succumb to the force and created a twitter account.

Bundling Gems in Jars/Wars for Jruby

Posted by boneill42 on February 1, 2012 at 8:15 AM PST

 

As part of Virgil's ability to deploy ruby scripts to a remote Hadoop cluster, we needed to package gems' into that Hadoop jar.  After a bit of monkeying around, we got it.

In response to a few requests for a binary distribution, we just posted artifacts for Virgil.

Hadoop/MapReduce on Cassandra using Ruby and REST!

Posted by boneill42 on December 1, 2011 at 11:21 AM PST

 In an effort to make Hadoop/MapReduce on Cassandra more accessible, we added a REST layer to Virgil that allows you to run map reduce jobs written in Ruby against column families in Cassandra by simply posting the ruby script to a URL. This greatly reduces the skill set required to write and deploy the jobs, and allows users to rapidly develop analytics for data store in Cassandra.

Concurrent use of embedded Ruby in Java (using JRuby)

Posted by boneill42 on November 30, 2011 at 11:28 AM PST

Last night, I was finishing up the map/reduce capabilities within Virgil. We hope to allow people to post ruby scripts that will then get executed over a column family in Cassandra using map/reduce. To do that, we needed concurrent use of a ScriptEngine that could evaluate the ruby script.

Introducing run-modes to Virgil: support for embedded or remote cassandra instances

Posted by boneill42 on November 28, 2011 at 7:35 PM PST

Since Virgil was originally developed as an embedded REST layer for the Cassandra Server, it ran as a daemon inside the server and performed operations directly against the CassandraServer classes.
