PolyScale brings automated caching to Neon databases, allowing users to minimize load on their database while providing sub-millisecond responses for cached queries globally. With the integration, users can set up caching for all queries in a few clicks and with a simple change to their database connection string. PolyScale's algorithms determine what to cache and for how long, ensuring 100% automatic invalidation of stale data through its Smart Invalidation system. The system leverages multiple layers of analysis to identify caching opportunities, providing highly scalable and performance-optimized solutions. By combining PolyScale with Neon, users can maximize the capability of their database, reducing latency access to cached queries globally while minimizing load on the database itself. With PolyScale's in-built performance test, users can see exactly how much latency reduction they can get from anywhere in the world when adding PolyScale to their project.
