Writing Policies for Caching
Explore the three main caching write policies—write-through, write-back, and write-around—and understand their impact on data consistency and system performance. This lesson helps you evaluate the best caching strategy to meet specific distributed system requirements and manage trade-offs between latency and data freshness.

The methods used to write data on a cache are called writing policies. In this lesson, we will discuss three caching types.
Write-through cache
In this caching technique, when a request is received, data is written on the cache and also on the database. This can happen either in parallel or one after another.
In this strategy, the cache will hold the most recently written data. And it will be consistent with the ...
