Description:

Mod_ndb is an Apache module that provides a Web Services API for MySQL Cluster.
It creates a direct connection from an Apache Web server to the NDB data nodes
in a MySQL Cluster (bypassing mysqld, and eliminating the need to create or
parse SQL queries). This allows you to query and modify a database over HTTP
using GET, POST, and DELETE requests, and retrieve results in a variety of
formats, including JSON results that can go 'direct to the browser' in an AJAX
application. Mod_ndb is also scriptable, using Apache's subrequest API, so that
complex multi-table transactions or joins (even including sort-merge join plans
that are currently not possible in MySQL) can be easily created in PHP or Perl.
