It's designed for functions that are expensive to run and produce large return values\u2014cases where in-memory caching would be wasteful. Each cached result is keyed by the function's arguments, so different argument combinations trigger fresh execution. You specify a cache lifetime in days; after that period, the cached file is deleted on the next module import.\n\nThe package provides three main functions: the @cache_to_disk(n_days) decorator itself, a delete_disk_caches_for_function() utility to manually invalidate a function's cache, and a cache_info() method to inspect hit/miss statistics. It also supports a NoCacheCondition exception to prevent caching in error scenarios while still returning a partial result.","worth_installing":"Yes, if you need simple, argument-aware disk caching for expensive functions and can accept dormant maintenance. The package is permissive-licensed, has no dependencies, and installs easily. However, the last update was in 2021\u2014if you need active support, bug fixes, or compatibility with future Python versions, consider alternatives or be prepared to maintain a fork."},"id":"cache-to-disk","links":{"html":"https://skillfed.io/packages/cache-to-disk","md":"https://skillfed.io/packages/cache-to-disk.md","pypi":"https://pypi.org/project/cache-to-disk/"},"maintenance":{"status":"dormant"},"meta":{"latest_release":"2021-12-07","license_spdx":null,"license_treatment":"permissive","name":"cache-to-disk","python_support":"unspecified","summary":"Local disk caching decorator for python function."},"popularity":{"monthly_downloads":110646,"position":12448,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.0.0"}
