Overview

cache-killer is an advanced cache invalidation tool designed to maintain the consistency between your database and cache seamlessly. The primary goal of cache-killer is to simplify the process of cache management by automating the cache invalidation process. It aims to improve the traditional 'update-then-invalidate' model by parsing database changes and handling the cache invalidation automatically.

Features

• Automatic Cache Invalidation: cache-killer listens to database changes and invalidates cache entries without the need to explicitly code the cache delete operations.
• MySQL Support: Currently, cache-killer supports MySQL databases by reading binlog events to parse update and delete operations.
• Cache Key Convention: It uses a convention schema:table_name:primary_key to form the cache key patterns which are then used to invalidate the corresponding cache entries.
• Retrying Mechanism: For any cache invalidation failures, cache-killer places the keys into a retry queue and a scheduled task attempts deletion again.
• Failure Notification: Upon reaching the maximum retry limit, cache-killer alerts the system administrator for manual intervention.
• Planned Support for Additional Databases and Caches: Future enhancements include extending support to PostgreSQL and other caching databases.

Current Limitations

• Supports only MySQL and Redis.
• PostgreSQL and other caching solutions are planned for future releases.
