I’ve spent a better part of the last year building Frigatebird, a high performance columnar SQL database written in Rust. The goal wasn't just to "make it work" but to use every systems programming trick available to maximize throughput on Linux. Frigatebird is an OLAP engine built from first principles. It features a custom storage engine (Walrus) that uses io_uring for batched writes, a custom spin lock allocator, and a push based volcano execution pipeline. I explicitly avoided async runtimes in favor of manual thread scheduling and atomic work stealing to maximize cache locality.

currently it only supports single table operations (no JOINS yet), would love to hear your thoughts on it
