How to: Write-around cache
![write-around-cache](https://raw.githubusercontent.com/karanpratapsingh/portfolio/master/public/static/courses/system-design/chapter-I/caching/write-around-cache.png)

Where write directly goes to the database or permanent storage, bypassing the cache.

**Pro**: This may reduce latency.

**Con**: It increases cache misses because the cache system has to read the information from the database in case of a cache miss. As a result, this can lead to higher read latency in the case of applications that write and re-read the information quickly. Read happen from slower back-end storage and experiences higher latency.
