The system that manages rate limits for both the Pinterest API and Ads API is built in Elixir. Its 50 percent response time is around 500 microseconds with a 90 percent response time of 800 microseconds. Yes, microseconds.<p>&quot;We’ve also seen an improvement in code clarity. We’re converting our notifications system from Java to Elixir. The Java version used an Actor system and weighed in at around 10,000 lines of code. The new Elixir system has shrunk this to around 1000 lines. The Elixir based system is also faster and more consistent than the Java one and runs on half the number of servers.&quot;<p>These are pretty strong claims, I think.
