I've got a question regarding the implementation of a caching system that I'm porting over from C.
I have multiple processes across an array of systems that must retrieve data from a central database at a fairly high rate. The current system uses shared memory and supports expiry after a configurable time limit, negative caching, and intent-to-write locking. Each process attaches to a shared memory segment that serves as a local cache for that system. My first notion was to implement memcached but I'm running in a shared environment and memcached does not provide for any type of authentication mechanism.
From what I understand, my other options would be mmap, or to go with one of
the Python IPC modules (though it appears most of those packages are listed in an Alpha/Beta state). Is there a better way to implement such an animal in Python? I feel like I'm trying to reimplement something that probably already exists. Thanks Jeff
