cache-collector

This plugin solves a common performance issue for large sites using object caching: managing and purging dynamically generated cache keys. It is designed for developers who need to maintain cache integrity when content updates, especially when cache keys are hashed values or part of complex groups. By registering keys in logical collections, it removes the manual burden of tracking and invalidating numerous individual cache entries.

• Dynamic Key Registration: Automatically records cache and transient keys into named collections when the data is first stored. This eliminates the need to recalculate hashed or complex keys later for purging.
• Bulk Collection Purging: Clear all cache entries within a specific collection using a single function call or WP-CLI command. This is useful for flushing all cached data related to a feature or data source.
• Post and Term Associations: Link cache keys directly to specific posts or taxonomy terms. When that content is updated, all associated cached data is automatically purged, ensuring front-end content remains fresh.
• Automatic Cleanup: Registered keys include a time-to-live (TTL). The system automatically removes expired keys from collections to prevent bloat and maintain performance.
• Memcache Group Support: Provides a method to purge all keys within a cache 'group,' which standard Memcache does not support natively, by using collections as a proxy.
