What are the top caching strategies? Read data from the system: 🔹 Cache aside 🔹 Read through Write data to the system: 🔹 Write around 🔹 Write back 🔹 Write through The diagram below illustrates how those 5 strategies work. Some of the caching strategies can be used together.
**Write-through**: data is written in cache & DB; I/O completion is confirmed only when data is written in both places
**Write-around**: data is written in DB only; I/O completion is confirmed when data is written in DB
**Write-back**: data is written in cache first; I/O completion is confirmed when data is written in cache; data is written to DB asynchronously (background job) and does not block the request from being processed
What is the difference between Cache Aside and Write Around? I know You've answer below, but, I didn't get, Could you elaborate on that more?
I think the diagram is just missing the pros and cons of each strategy.
What is the difference between write-around and cache-aside? They both seem very similar.
