Dear cqlsh: Your dependencies were killing us (P.S. We rewrote you in Rust)

This post details the motivation and process behind rewriting the Python cqlsh tool in Rust. Key technical drivers include eliminating Python dependency management nightmares, improving the reliability and performance of the COPY TO/FROM feature, and achieving a static binary with zero runtime dependencies. The post highlights the challenges of vendoring dependencies in the Python version and the benefits of Rust's compilation model for deployment and maintenance. It also touches upon the use of AI (Claude Code) as a tool in the development process.
