Cloudflare says Hyperdrive MySQL support is GA after beta fixes and a rare caching-bug investigation

Cloudflare says Hyperdrive support for MySQL is now generally available after a beta focused on reaching a 99.99% production availability target and fixing about 20 issues. The article details fixes for UTF-8 handling, connection reset encoding, and a rare bug causing empty query responses about 0.001% of the time only when caching was enabled.

For teams using Workers with MySQL, Hyperdrive caching can reduce latency and origin load, but the reported bug shows that shared cache behavior and MySQL protocol capability translation need validation with real client libraries. The practical trade-off is performance versus subtle correctness risk; the supplied text flags mysql2’s lack of CLIENT_DEPRECATE_EOF support but does not include the final root cause or patch details.
