Cut DNS Build Delay and Memory Use by 85% with Targeted Zone Builds

Cloudflare's DNS zone builds were taking a long time and consuming a lot of memory. The solution was to implement targeted zone builds, which select the smallest safe build size based on the zone's size and changes.

This approach reduces the need for full zone rebuilds, which can take hours or even days. By only rebuilding the necessary parts of the zone, you can cut build delay in half and reduce peak memory usage by 85%.

This is a great example of how optimizing your infrastructure can have a significant impact on performance and resource usage. If you're a webmaster or server host, consider implementing targeted zone builds to improve your DNS performance.
