To improve performance and reduce database load, I’ll implement caching.

Caching stores frequently accessed data temporarily so repeated requests don’t hit the database every time.

In Spring Boot, I can use:
1. Spring Cache
2. Redis
3. EhCache
4. Caffeine Cache

For example, if product or user profile data changes rarely, caching can significantly reduce response time.

I’ll also:
• Configure cache expiration time
• Evict cache after updates
• Avoid caching sensitive or highly dynamic data
• Monitor cache hit and miss ratio

Proper caching improves scalability and reduces database pressure during high traffic.
