Summary

Harper Redirector is a specialized redirect management tool designed to handle millions of redirects with sub-millisecond lookup times, eliminating the need for additional databases, caches, or edge workers. It addresses the limitations of legacy systems like Apache and Nginx by using horizontally sharded tables and in-memory indexes to efficiently manage redirects, providing a seamless solution for scaling and latency issues. The tool simplifies operations by consolidating redirects into a single CSV/JSON import or via REST API calls, supporting host-aware lookups, regex paths, and query-string operations. Harper Redirector offers instant metrics tracking and versioning capabilities, allowing atomic swaps of redirect sets, making it ideal for platform transitions. It can be deployed on a single VM, a Kubernetes cluster, or across geo-distributed edge nodes, offering flexibility in architecture design and enabling quick scaling by simply adding more nodes. Users can test the system locally with a straightforward setup process and deploy it to various environments without downtime using the Harper CLI.
