Ever wondered how to store millions of call stacks efficiently? So did we. Many times.

Check out this new article by Jelle about designing a data structure to efficiently compress and store large amounts of call stack data!

Compressing callstacks: a bitpacked DAG powered by a keyless hashmap - Superluminal %

In Superluminal we need to store potentially millions of callstacks very efficiently. This article describes how we went from naive storage taking up gigabytes of memory in the worst case, to a very compact data structure that efficiently compresses and stores large amounts of stack data in a fraction of the memory.
