mod_ndb 1.1 is now available at http://code.google.com/p/mod-ndb
mod_ndb is an interface to MySQL Cluster that runs inside an apache
web server. It does not use MySQL servers, but communicates directly
with cluster data nodes using the low-level NDB API.
This version contains built-in support for the server side of Doug's
JSONRequest proposal (http://www.json.org/JSONRequest.html)
. It also
can use JSON in general as an input format for HTTP requests and an
output format for database responses.
