Achieving P99 0ms Autocomplete for 240M Domain Names on Wirewiki.com
Key points
- Wirewiki.com uses client-side prefetching and caching.
- API searches Tranco list first, then CZDS for domain names.
- P99 0ms latency means results are ready before key release.
- The system handles 240 million domain names.
Background on Wirewiki.com
Wirewiki.com is a website designed to inspect internet infrastructure, such as domain names, DNS records, and email deliverability configurations. The site aims to differentiate itself through tool quality and user experience in a competitive market.
Autocomplete as a Core Feature
The autocomplete function is the primary navigation method for Wirewiki.com. The goal was to make this feature instant, with suggestions appearing before the user releases a key. This required a technical solution to minimize latency.
Technical Implementation for Speed
The system uses client-side prefetching and caching. When a user presses a key, suggestions for that character and the next potential character are prefetched. Upon key release, the suggestions are rendered. This strategy leverages the time between key presses to prepare results.
The definition of P99 0ms latency in this context means that 99% of the time, the autocomplete results are ready for rendering before the user lifts their finger from the key. This is achieved within a measured P99 budget of 121 ms for typical typing speeds.
API Design and Data Sources
The backend API is designed for speed, first searching the Tranco list of the top 1 million most popular domains. If additional domains are needed, it then queries the CZDS list, which provides domains for most gTLDs. Other potential data sources like certificate transparency logs and Archive.org are noted for future integration.
