Earlier this summer, the Go team released version v0.12 of gopls, the language server for Go, featuring a rewrite of its core that allows it to scale to larger codebases.
Since then, we've fine-tuned the design, focusing on making interactive queries as fast as they were with v0.11, despite holding less state in memory.

You probably know about Russ Cox's blog post about sparse maps:
https://research.swtch.com/sparse
This data structure is used in #golang source code (mainly inside the compiler).
I came up with another idea that can work even faster:
