Replay events to rebuild application state. 4. Show how to append, retrieve, and process events from Redis in Symfony services. Additional considerations: 1. Ensure event ordering and idempotency. 2. Support event versioning or migration. 3. Optionally, integrate with other event stores or message brokers. Expected output: A Symfony code sample using Redis for event sourcing and state reconstruction.
# Prompt 8: Redis Rate Limiting in Symfony Help me write Symfony code to integrate Redis cache Code requirements: 1. Implement API rate limiting using Redis to store request counters per user or IP. 2. Use Symfony's RateLimiter component configured with Redis as the backend. 3. Define rate limit rules (e.g., 100 requests per minute) and custom responses when limits are exceeded. 4. Show code for checking and updating rate limits in middleware or controllers. Additional considerations: 1. Provide informative headers for rate limit status in responses. 2. Optionally, store rate limit logs for monitoring. 3. Test with concurrent requests for robustness. Expected output: A Symfony app with Redis-backed API rate limiting and proper user feedback.
# Prompt 7: Redis Cache with Custom Serialization in Symfony Help me write Symfony code to integrate Redis cache Code requirements: 1. Store complex objects (e.g., Doctrine entities, arrays) in Redis cache using custom serialization (e.g., JSON, PHP serialize). 2. Implement custom normalizers or encoders if needed. 3. Retrieve and unserialize the cached data safely in Symfony controllers or services. 4. Handle serialization errors gracefully and log problems. Additional considerations: 1. Avoid versioning issues with object serialization. 2. Test custom serialization with evolving object schemas. 3. Document serialization strategies for the team. Expected output: A Symfony example showing custom serialization/deserialization for Redis cache.
# Prompt 6: Redis Cache Tags and Invalidation in Symfony Help me write Symfony code to integrate Redis cache Code requirements: 1. Use cache tags to group related cached items in Redis. 2. Invalidate a group of cache entries using a tag-based system (e.g., clear all product-related cache on product update). 3. Show how to add, retrieve, and invalidate cache tags in Symfony code. 4. Document best practices for tag naming and maintenance. Additional considerations: 1. Handle tag invalidation for complex object graphs. 2. Optionally, expose tag-based cache clearing via an admin endpoint. 3. Monitor tagged cache usage for performance. Expected output: A Symfony project implementing cache tags and group invalidation using Redis.
# Prompt 5: Using Redis Pub/Sub with Symfony Messenger Help me write Symfony code to integrate Redis cache Code requirements: 1. Configure Symfony Messenger component to use Redis transport for real-time messaging. 2. Demonstrate sending and receiving messages with Redis Pub/Sub channels. 3. Create a Symfony command or service that listens to a Redis channel and processes messages. 4. Handle message acknowledgment and retries. Additional considerations: 1. Ensure Messenger worker resilience with Redis outages. 2. Optionally, integrate with real-time front-end updates (e.g., WebSockets). 3. Document pub/sub topic naming conventions. Expected output: A Symfony app using Redis Pub/Sub for real-time message processing with Messenger.
# Prompt 4: Redis as Symfony Session Storage Help me write Symfony code to integrate Redis cache Code requirements: 1. Configure Redis as the session storage backend in `config/packages/framework.yaml`. 2. Store and retrieve session data using Symfony's session API. 3. Handle session expiration and garbage collection via Redis settings. 4. Show code examples for reading and writing to the session in a controller. Additional considerations: 1. Support session migration for legacy data if needed. 2. Secure session data with proper Redis ACL or firewall settings. 3. Test concurrent session access and session locking. Expected output: A Symfony application using Redis to store and manage session data.
# Prompt 3: Redis Cache for HTTP Response Caching Help me write Symfony code to integrate Redis cache Code requirements: 1. Configure Symfony HTTP cache to use Redis as the storage backend. 2. Set up cacheable responses in controllers using HTTP cache headers (e.g., `Cache-Control`). 3. Show how to cache entire pages or API responses. 4. Provide a cache purge endpoint to invalidate specific URLs or tags. Additional considerations: 1. Use cache tagging or versioning for granular invalidation. 2. Handle cache busting on data changes. 3. Monitor cache hit/miss rates for optimization. Expected output: A Symfony project with Redis-based HTTP response caching and manual purge capability.
# Prompt 2: Redis Cache for Doctrine Results in Symfony Help me write Symfony code to integrate Redis cache Code requirements: 1. Configure Redis as the cache provider for Doctrine ORM in Symfony (`config/packages/doctrine.yaml`). 2. Cache Doctrine query results to improve performance on repeated database queries. 3. Show example usage of the Doctrine result cache with Redis backend. 4. Provide a method to clear or refresh the cache for a specific query. Additional considerations: 1. Ensure cached data is invalidated when underlying entities change. 2. Document how cache regions and lifetimes work with Redis. 3. Test with large datasets to measure efficiency. Expected output: A Symfony setup where Doctrine ORM uses Redis for result caching and refresh.
# Prompt 1: Basic Redis Cache Integration in Symfony Help me write Symfony code to integrate Redis cache Code requirements: 1. Install the `symfony/cache` and `symfony/redis-messenger` packages if not already present. 2. Configure Redis as the default cache adapter in `config/packages/cache.yaml`. 3. Use Symfony's `CacheInterface` to set and get cached values in a controller. 4. Demonstrate cache set, get, and delete operations for a sample key/value. Additional considerations: 1. Validate Redis connection and fallback gracefully if unavailable. 2. Test cache performance with large payloads. 3. Optionally, clear the cache via a Symfony command. Expected output: A Symfony project with Redis as the cache backend and basic cache usage in a controller.
