24 alternatives to FunctionCacher, a Python cache-to-disk utility
The FunctionCacher Python utility provides a way to cache the result of a (computation- or IO-heavy) function call to a location on the filesystem, ideally onto a ramdisk/tmpfs. This allows caches to exceed the lifetime of the program, which is useful for rapid-prototyping (& rapid-crashing) scripts. Caches are generated based function name, parameters, and code.

I am the author of the platform, happy to reply to any question you might have! It scales up really nicely thanks to a year of research and development of the hashtable implemented in cachegrand, on the hardware used for benchmarking, an AMD EPYC 7502P, it was able to reach up to 5mln GET QPS and 4.5mln SET QPS, with batching up to 60mln GET QPS and up to 26MLN SET QPS. cachegrand is fast, it's fully Open Source, it's under a BSD 3-clause license - it can be used easily as standalone platform or incorporated in other ones without any licensing issue - and we are working to expand the Redis…
