Time and order are one of the most complex problems in distributed systems. The other connected problem is that there can not be a perfect solution, because that would involve changing some physics laws, and those are quite hard to change :-).

There are multiple solutions to the problem, and I believe the article can be a great starting point since it has multiple interesting links about this problem and how other solved it.

It’s a great reading for anyone involved in distributed systems or anyone interested in learning new complex problems that they may not have been thought about.

I didn’t know about the Bloom filter data structure. This article is a very simple explanation of what is a Bloom filter and some examples of who is implementing it and how.

It’s interesting also this that was linked at the end of the article when other developers are showing more examples of companies using this data structure.

Everyone probably knows about Quora. It’s a website where anyone can ask questions and someone may answer it.

In this case, this is the question, and who answered it is Alan Kay, and maybe you don’t know him, but he is (also) known as the “inventor” of Object-Oriented Programming, hence why this answer is extremely detailed and interesting.

I’m not saying anything further. If you are curious about his answer you can read it.

Netflix always has interesting technical articles about the technologies they develop to solve actual problems, and often they release a lot of their code open source.

This article is explaining a new method they are using to find the limit of concurrent request a service can handle. They developed a tool that uses the TCP congestion control algorithm to find out the limit of the concurrent request of an “unknown” service, then use this value to automatically set the capacity limit to not overstress the service. This previously was doing manually for each service.
