By Xiaomei Liu , Rosanna Lee , Cyril Concolato Introduction Behind the scenes of the beloved Netflix streaming service and content, there are many technology innovations in media processing. Packaging has always been an important step in media processing. Uploading and downloading data always come with a penalty, namely latency.

The Solution: Distributed Caching. A widely used technology called distributed caching meets this need by storing frequently accessed data in memory on a server farm instead of within a database. It’s not enough simply to lash together a set of servers hosting a collection of in-memory caches.

But since retrieving data from disk is slow, databases tend to work with a caching mechanism to keep as much hot data, the bits and pieces that are most often accessed, in memory. In MySQL, considering the standard storage engine, InnoDB , the data cache is called Buffer Pool. In PostgreSQL, it is called shared buffers.

ISPs do cache DNS however which means if your first provider goes down it will still try to query the first DNS server for a period of time before querying for the second one. But remember, ISPs also cache the DNS so by setting a longer TTL it means fewer queries to your DNS servers. So DNS services definitely go down!

Examples of this might be, expecting that the HTML is fully static, such that we can cache it downstream in some deterministic manner — “partially dynamic” HTML bodies are much more likely to be handled incorrectly by caching logic. In this case, we can’t expect each layer could/should process and inject HTML content.

This is mainly because video files are notably bulkier than a simple text-based API request, which, in comparison, would be more like a droplet than an entire river.
