Faster dashboards via Redis caching for Athena queries
Every Athena-backed query in the dashboard API is now cache-fronted by Redis. Repeat loads of the same time window return in milliseconds instead of seconds.
The big analytics pages — Traffic, Bots, Paths, IPs, Geography, Status Codes, the SEO suite — all run Athena queries against your S3 log archive. Athena is fast for ad-hoc analytics but it's not millisecond-fast, and reloading the same view (or sharing a link with a teammate who loads the same view a minute later) used to re-run the query from scratch.
We've now wrapped every Athena query function in the dashboard API with a short-TTL Redis cache. First load still pays the Athena cost; every load after that on the same window comes back from Redis in milliseconds. Cache TTLs are short enough that fresh data still flows in normally — you won't see stale numbers.
