  31 2,307 7.6 C++

  A family of header-only, very fast and memory-friendly hashmap and btree containers.

  https://github.com/greg7mdp/parallel-hashmap has a full write up on memory improvements over the equivalent C++. There’s a reference implementation I did in Rust here https://github.com/nkconnor/sharded focused on the concurrency side.

• sharded
