fragmented-keys

Fragmented Key Management and Invalidation Library for use with Redis.

A Python port of noizu-labs/fragmented-keys (PHP), adapted to use Redis as the cache backend.

Fragmented Keys enable efficient cache invalidation by composing cache keys from multiple independently versioned tags. Instead of deleting cached entries individually, you increment a tag’s version — all keys that depend on that tag automatically resolve to a new cache key, leaving the old entries to expire naturally.

Cache Key = md5( base_key + tag1:version1 + tag2:version2 + ... )

When any tag version changes, the resulting key changes, producing a cache miss and triggering a fresh data fetch.
