You can use the ngx_rds_json module to emit JSON from the RDS reply
generated by ngx_drizzle (and ngx_postgres), and use a decent lua JSON
library like lua-cjson or lua-yajl to parse it into Lua data
structures and proceed processing.

PHP and the Embedded Perl addon are all blocking on backend requests
to mysql/postgres/redis/whatever. The penalty and impact of the latter
is more serious if one does not start *many* nginx worker processes.
Well, anyway, if one doesn't care about performance, especially
concurrency, then whatever methods can be used :)
