Connect to Redis<\/h2>\n<p>Install the client and create a connection: <code>import redis; cache = redis.Redis(host='localhost', port=6379)<\/code><\/p>\n<h2>2. Use the Cache-Aside Pattern<\/h2>\n<p>First check the cache; on a miss, load from the database and store the result with a TTL.<\/p>\n<ul>\n<li><code>cache.get(key)<\/code> \u2014 checks the cache.<\/li>\n<li><code>cache.set(key, value, ex=300)<\/code> \u2014 stores for 5 minutes.<\/li>\n<\/ul>\n<h2>3. Invalidate Stale Data<\/h2>\n<p>When the underlying data changes, delete or refresh the key.<\/p>\n<ul>\n<li><code>cache.delete(key)<\/code> \u2014 removes the key.<\/li>\n<li><code>cache.set(key, new_value)<\/code> \u2014 updates it immediately.<\/li>\n<\/ul>\n<h2>4. Follow Best Practices<\/h2>\n<ul>\n<li>Always set a TTL to avoid memory buildup.<\/li>\n<li>Use <code>decode_responses=True<\/code> for readable strings.<\/li>\n<li>Handle Redis downtime gracefully by catching exceptions.<\/li>\n<li>Name keys with a prefix, e.g., <code>user:123<\/code>.<\/li>\n<\/ul>\n<p>Redis caching is straightforward once you know the core patterns. Start simple, measure the hit ratio, and tune the TTLs accordingly.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>How to Implement Caching with Redis: A Practical Guide Caching reduces database load and speeds up your application.
