Caching strategies explained

Write-Through Cache: Data is written to cache and database simultaneously.
Ensure Data Consistency

Example: A retail website ensuring inventory updates are consistent.

Write-Back Cache: Data is written to the cache first and database asynchronously.
Ensure Low Latency

Example: Online gaming systems saving player stats.

Read-Through Cache: Data is fetched from the database and stored in cache for future requests.
Read heavy apps/Slow db

Example: Frequently viewed product pages.

Cache Aside: Application queries cache first; if data isn’t there, fetches from the database and write to cache.
Application manages cache

Example: Social media profile data.
