Leader Election With Ruby & PostgreSQL

The Problem

I have a table with millions of rows that needs processing. The type of processing is not really important for this article. We simply need to process some data with Ruby --or any other user-space programming language.

A Solution

 -- PostgreSQL 9.2 beta (for the new JSON datatype)
 --   You can actually use an earlier version and a TEXT type too
 -- PL/V8 http://code.google.com/p/plv8js/wiki/PLV8

 -- Inspired by 
 -- http://people.planetpostgresql.org/andrew/index.php?/archives/249-Using-PLV8-to-index-JSON.html
 -- http://ssql-pgaustin.herokuapp.com/#1

  -- JSON Types need to be mapped into corresponding PG types
