Repository metrics are context, not quality scores. Active installations measure adoption and can strongly reflect a plugin’s age and historical popularity. Ratings, recent updates and “Tested up to” metadata also do not guarantee modern code, error-free operation, security, feature completeness or suitability for a particular site.

WP PlugIndex currently records PigCache version 1.0.29 as active, updated 1mo ago and tested up to WordPress 7.1.
Overview
About this plugin
PigCache replaces WordPress’s default object cache with Redis (official drop-in pattern), using PhpRedis when available or the bundled Predis. php.
Features:
Redis object cache drop-in (PhpRedis or bundled Predis)
SQL query cache (optional db.php drop-in) with per-table invalidation, so writing to one table does not discard results that never read it
Full-page HTML cache for anonymous visitors with tag-based selective invalidation on content changes
Fragment caching helpers backed by Redis
Tag-based selective invalidation — only affected pages are purged when a post, term, or comment changes
Every feature listed above is included and fully enabled. The plugin has no license check, no trial period and no usage limit, and it does not contact any external service.
The object cache drop-in is derived from Redis Object Cache (GPLv3, Till Krüss / Rhubarb Group).
External services
This plugin does not connect to any external service. All caching, invalidation and metrics happen on your own server and your own Redis instance.
