An article on tweaking Twitter's architecture.

This article presents a series of four case studies of how real time APIs were implemented.Artificial Neural Networks offer significant performance benefits compared to other methodologies, but often at the expense of interpretability.

Same for the queues: input stream queue should be really fast, while friend stream update queue might be slightly slower.

Let’s think about the queues.

The Rails front end handles rendering, cache composition, DB querying and synchronous inserts. I failed to find Twitters actual architecture diagram or an article containing an overview about it.What does Twitter's architecture diagram looks like?It would be difficult to find a single, grand architecture diagram explaining all Twitter services.

Twitter is one of the most complicated distributed systems deployed as for now, and it is really interesting to understand how it works under the hood.If you pretend to be a distributed systems architect, the common question on your interview would looks like this: “.First of all, let’s start with the requirements for our system and some simple SLA we will try to meet.
