I've spent the past couple months hand crafting a new B-tree map implementation for Go. It's fast. Faster than Rust's BTreeMap. Faster than the fastest C++ (frozenca/btree). And about 2x faster than my current Go btree (tidwall/btree).

Yeah it really does just work. Why implement a btree on top of the perfectly good btree your OS already has?

This new Go B-tree implementation looks both fast and pleasant!
(This is from @tidwall.bsky.social, who has done very nice things in the #golang world like tile38, gjson, prior btree, ...)

After many months of planning and development, here it is.
Introducing btype. B-tree based collection types for Go.
It's hand-crafted to be faster than the current B-trees for Go, Rust, and C++.

God bless Iterator::collect. I know we all love to praise the Entry API and the BTree `range` API but it’s easy to forget just how wonderful and beautiful `Iterator::collect` is.

Spent the past couple days playing with Zig. I wrote myself a little rtree and btree. It's fast and comptime is really cool.

Did just realize there is actually a BTree structure in the swift-collections package but it’s not released yet 😔
