By simply swapping your connection string for a PolyScale one, all queries are routed through the nearest PolyScale Point of Presence (PoP), which automatically caches read results, manages TTLs via machine learning, and invalidates stale data globally using a three-layer Smart Invalidation system. The caching algorithms analyze query arrival rates, change rates, and query templates to determine what to cache and for how long. Smart Invalidation parses SQL at the row level, falls back to table-level invalidation for complex queries, and uses empirical monitoring to disable caching for queries with unexplained data changes. A built-in performance test lets users compare direct database latency versus PolyScale-cached responses from any global region, with example results showing improvements from 90ms to sub-1ms. ## Full article daily.dev links to this article rather than hosting it.
