What are the best practices for cache optimization?

Cache optimization involves strategies to improve data retrieval speed and efficiency. Key practices include using appropriate cache sizes, implementing cache expiration policies, and choosing the right caching algorithms.

Can you explain how cache expiration policies work?

Cache expiration policies determine how long data remains in the cache before it is considered stale. Common strategies include time-based expiration, where data is removed after a set period, and event-based expiration, which clears data based on specific actions.

What caching algorithms should I consider?

Some popular caching algorithms include Least Recently Used (LRU), First In First Out (FIFO), and Least Frequently Used (LFU). Each has its strengths depending on your use case.

How can I measure the effectiveness of my cache?

You can measure cache effectiveness using metrics like hit ratio, which indicates the percentage of requests served from the cache, and latency, which measures the time taken to retrieve data.
