What does HackerNews think of hashmap?

A Golang lock-free thread-safe HashMap optimized for fastest read access.

Language: Go

#84 in Go
#76 in Go
I generally just use this one: https://github.com/cornelk/hashmap

Mostly in that it also gives me lock free performance, which cleans up a lot of defers.

Glad to see this make it into the core.

I've been using this library for ages now...

https://github.com/cornelk/hashmap

Always entertains me to see developers write all the lock/unlock code when they could just use that.

Agree, but I can't recall ever seeing a package in the wild that labels itself as "concurrency-safe" and yet requires the caller to explicitly call Lock!

HashMap is probably a good example

There's some context missing here. AFAIK the author of the repositories was specifically doing micro-benchmarks here to inform the design of his https://github.com/cornelk/hashmap library. I think for that use case (designing a high-performance lock-free data structure), that kind of micro-benchmarking makes a lot of sense.

That hash map looks good and I'm thinking we'd probably benefit from using it on the hot path of some code we have that needs to be highly scalable.
