To anybody unfamiliar with recent progress, boost::unordered_flat_map is the fastest open-addressing hash map implementation in this field for C++. Coming out just several months ago, it outperforms absl::flat_hash_map and various other implementations benchmarked in https://martin.ankerl.com/2022/08/27/hashmap-bench-01/.

It's a little hard to take seriously some of the top performers in that table, like emhash8, when the implementations are only a couple of weeks old and the commits are things like "fix crash", "fix clear", and "fix overflow".

Uhh.. super irrelevant--being web scale is the most important attribute.

I think I need more context for whet you’re trying to say here. I understand “web scale” in the marketing term Mongo sense but I don’t know how that applies to this

I’m pretty sure they’re being sarcastic.

That link does not have boost unordered_flat_map?
