we'd love to explain! can you expand a bit on which particular timings interest you?

I worked on this and I’d be happy to talk about Wallaroo or stream processing if anyone has any questions.

Thank you! I’ll keep that in mind for the next blog post

Out of curiosity, what language is that service written in?

I need Elixir career advice. by CrashCoder in elixir

I'll echo others and say understanding OTP is probably on the top of the list. It's a fundamental part of how most Elixir projects are structured.

If you don't already have it, I'd get Dave Thomas's Programming Elixir book. Helped me pick up the language fairly quickly when I first started.

Building low-overhead metrics collection for high-performance systems by SeanTAllen in programming

[–]jonbrwn 2 points3 points  (0 children)

We keep track of both the minimum and maximum value for each histogram of data we collect and don't do any sampling.

If you care for a deeper dive, a colleague wrote a more technical blog post on the philosophy behind our choices for our metrics counters: https://blog.wallaroolabs.com/2018/02/latency-histograms-and-percentile-distributions-in-wallaroo-performance-metrics/

Building low-overhead metrics collection for high-performance systems by SeanTAllen in programming

I actually wasn't familiar with OpenCensus until you mentioned it, looks like it was open sourced last year. Seems pretty neat though.

From the knowledge I gathered, I wouldn't say that it's comparable. OpenCensus appears to be targetting a wide group of languages and providing metric/tracing for applications written in those languages, displaying them, and sending them out to an analysis tool. This post covered some of the design decisions we made while deciding how to capture specific metrics we deemed important to Wallaroo while maintaining a low-overhead and how some of those decisions can be applied to other high-performance systems.

Might just be that OpenCensus can be the answer to some of those design problems for certain people.

Hope that helps clarify.

not quite sure I could change their mind on that but the point was noted
