Cache-Aside Pattern

Summary

The most common caching pattern: your application checks the cache first, and on a miss, reads from the database and populates the cache for next time.

• 1Implement cache-aside manually for one endpoint: check cache, miss, fetch, populate.
• 2Learn the 'thundering herd' problem when many requests miss the cache simultaneously.
• 3Compare cache-aside to letting your ORM or framework handle caching automatically.
