Cache Collector is a tool for developers working on large websites that use caching systems like Memcache. It addresses the challenge of purging dynamically generated cache keys, which are often hard to track and manage manually. By storing keys in collections, it enables efficient cache management and reduces errors in cache invalidation.

• Dynamic Key Registration: Automatically registers cache or transient keys when they are stored, linking them to specific collections for organized tracking.
• Bulk Purging: Purge entire collections of cache keys with a single command, eliminating the need to calculate or list individual keys.
• Post and Term Integration: Register keys related to posts or taxonomy terms, with automatic purging triggered when content is updated, ensuring cache consistency.
• WP-CLI Support: Includes a command-line interface for purging collections directly from the terminal, facilitating automation in development workflows.
• Expiration Management: Sets expiration dates for registered keys to automatically remove unused entries from collections, preventing performance degradation over time.
