Ask HN: What are some 'cool' but obscure data structures you know about?
54 projects | news.ycombinator.com | 21 Jul 2022
Tries (or prefix trees).
We use them a lot at Pyroscope for compressing strings that have common prefixes. They are also used in databases (e.g indexes in Mongo) or file formats (e.g debug symbols in macOS/iOS Mach-O format are compressed using tries).
We have an article with some animations that go into details about tries in case anyone's interested .
Question: How do you handle oversized heap analysis?

You could use continuous profiling with Pyroscope which uses async-profiler under the hood, but with the added functionality that you can add relevant tags to your VMs (example).
JFR (Java Flight Recorder) Parser written in Go
2 projects | reddit.com/r/golang | 19 Apr 2022
Java Flight Recorder (JFR) is a format for collecting diagnostic and profiling data from Java applications. A while back someone created an issue for Pyroscope , an open source continuous profiler written in Go, to support ingesting profiles in JFR format, but there were no existing parsers that were also written in Go.

Tries are also used to efficiently store names of functions in macOS / iOS binaries (Mach-O format) and work great for that purpose because a lot of functions have the same prefixes .
Indexes in mongodb use a similar concept (they call that prefix compression ), and that allows them to store indexes more efficiently.
We use them at Pyroscope and we wrote a blog post about our storage design  It has some animations too!

Pyroscope (YC W21) | Senior Software Engineer | REMOTE | Fulltime / Contract
Pyroscope is open source performance monitoring software, currently with a focus on Continuous Profiling. Pyroscope was founded at the beginning of 2021 and we've already seen a lot of rapid growth/community adoption as well as feedback for what features developers are excited for us to build.
We're looking for Senior Software Engineers for both frontend and backend. Our frontend uses React and Redux and our custom storage engine is written in Golang (with agents for many other languages as well)
* Interest in / experience with Open Source
* Performance analysis experience
* SRE experience
* Solid CS knowledge, particularly understanding of data structures (we use trees and tries extensively see https://github.com/pyroscope-io/pyroscope/blob/main/docs/sto...)
