Scaling and benchmarking a critical message bus using a new indexing strategy

A blog post from Jane Street discusses the challenges of scaling a critical message bus and presents a new indexing strategy to improve performance. The message bus in question is used by Jane Street's trading platform and handles a high volume of messages. The authors used a benchmarking framework to test the performance of the message bus and found that the new indexing strategy resulted in a 50% improvement in performance. The strategy involves partitioning the data into smaller segments and using a combination of hash tables and binary search to quickly locate messages. The post also includes a detailed explanation of the benchmarking process and the results.
