How I made a powerful cache system using Go
summary
A cache proxy called swan is written in Go and ships as middleware for Traefik, Caddy and others, using Badger or pluggable providers and a YAML config. It claims first call 14 ms then cached <3 ms, implements request coalescing via singleflight, exposes JWT‑protected APIs to list keys and purge by id/regex/tag, and runs as version 1.6.19. Configuration hot‑reload, TTL/tag invalidation, and async backend updates are implemented; benchmarks show thousands of requests with max latencies in the tens of milliseconds.
