What are the best practices for configuring Memcached?

What are the best practices for configuring Memcached?

When configuring Memcached, consider the following best practices: 1. Set appropriate memory limits, 2. Use consistent hashing, 3. Optimize your eviction policy, 4. Monitor performance regularly, and 5. Use multiple Memcached instances for scalability.

How do I choose the right eviction policy?

Choosing the right eviction policy depends on your use case. LRU (Least Recently Used) is great for caching frequently accessed data, while LFU (Least Frequently Used) can be better for data that is accessed less often but still needs to be cached.

What should I monitor in Memcached?

You should monitor metrics like cache hit ratio, memory usage, eviction count, and the number of connections to ensure optimal performance.

Can I use Memcached with a database?

Yes, Memcached can be used alongside a database to cache query results, reducing load times and improving application performance.

What are some common pitfalls to avoid?

Common pitfalls include not setting memory limits, failing to monitor performance, and using a single instance without redundancy.
