DESIGNING A FAST CONCURRENT HASH TABLE

Summary from the TLDR Web Dev newsletter

Papaya is a fast and concurrent hash table for Rust. It uses a novel approach to address the challenges of lock-free design, including using a metadata table for cache efficiency and a probabilistic approach to resizing. It also uses various memory reclamation strategies to be faster than other concurrent Rust hash tables in terms of read throughput, latency, and async support.
