Cloudflare makes Hyperdrive MySQL generally available after fixing a caching bug
Cloudflare published a post describing a MySQL protocol bug in Hyperdrive's query result caching, found while adding MySQL support, which produced a 0.001% rate error. The post states that Hyperdrive MySQL is now generally available.
Why it matters
Builders can now use Hyperdrive with MySQL databases, not only PostgreSQL. Teams that enable query result caching should review how the fix affects their cached reads.
Who should care
Backend developers, database engineers, and ecommerce or SaaS teams running MySQL behind Cloudflare Workers.
What you can do
Review Hyperdrive's MySQL documentation and test cached query behaviour in a staging Worker before enabling it in production.
