Oh, my pleasure ;)

In our production web sites, we're using ngx_lua to do full server
side web application development. It issues nginx subrequests to
internal nginx locations configured by ngx_drizzle, ngx_memc,
ngx_redis2, ngx_proxy (and many other upstream modules) to fire out
non-blocking queries to our (big) mysql clusters, memcached clusters,
tokyotyrant clusters, redis clusters, Taobao Open Platform (TOP) web
services, and many other internal backends.
We also intergrate our full-fledged SQL engine written in pure Lua
into nginx (by means of ngx_lua) to do complex relational data mash-up
of various different data-sources directly in memory. And we invented
LZSQL  which is a high-level language for abstracting away the
difference between SQL requires running remotely (i.e., in a mysql
node) and SQL queries running locally (i.e., directly within the nginx
core). Most of our business logic for data products is written in
