Hi All, I want to develop an Nginx HTTP module that gets several values from memcache, performs some processing on them and returns the result to the client. I want all memcache operations to be performed asynchronously without blocking the worker process for maximum scalability. For this reason, I can't use libmemcached, and I'm looking for something that is built on Nginx. Is anyone familiar with a piece of code that does that ?
Some more details: As I understand, it is theoretically possible to use the existing memcache upstream module for this, using subrequests. For example, to get a value I could start a subrequest for it and then handle the result when the subrequest completes. But this approach sounds a bit awkward, and it has the unnecessary overhead of processing all these dummy HTTP requests. What I would like ideally, is a module that exposes a function like - memcache_get(keyname, callback, context), where the callback is called either with the value if successful or an error code. I started writing such a module using the http_upstream module as reference, but found that it takes quite a bit of code to get it done, with lots of edge cases to handle (like timeouts in each one of the states) Thank you !
