What are the best practices for caching async requests?

What are the best practices for caching async requests?

The best practices for caching async requests include using a cache layer, setting appropriate expiration times, and ensuring cache invalidation.

Can you explain how to implement a cache layer?

To implement a cache layer, you can use tools like Redis or Memcached, which store data in memory for quick access.

What should I consider for cache expiration?

Consider the data's volatility, user access patterns, and how often the data changes to set appropriate expiration times.

How do I handle cache invalidation?

Cache invalidation can be handled through strategies like time-based expiration, event-based invalidation, or manual purging.

Are there any common pitfalls to avoid?

Yes, common pitfalls include over-caching, not considering cache size limits, and failing to monitor cache performance.
