Today we are pleased to announce support for across the network. Using PolyScale, users can now automatically cache database data locally to any of the Fly regions, for low-latency data access.

polyscale fly io header is a serverless, plug-and-play database cache. It dramatically accelerates database read performance, lowers network latency and reduces database infrastructure costs. PolyScale is plug-and-play requiring no code to implement, and zero configuration or tuning. It can be implemented in minutes with a simple configuration change. PolyScale offers a global edge network SaaS platform as well as a self hosted option.

Faster Data-driven Apps

PolyScale caching can be used to significantly accelerate data-driven application performance both for single and multi-region apps. Once connected PolyScale will intelligently cache repetitive queries within the same Fly region as the requesting application and hence upon a cache hit, queries will be executed sub-millisecond, no matter the query complexity.

Any Database Type, Any Database Vendor

With PolyScale on, Fly applications can now utilize any database hosting providers that may not be geographically close to a Fly region. This provides Fly users with cacheable data, unlimited choice for database hosting. This also enables user to migrate their application tier to Fly, without the overhead of a database migration.

Additionally, PolyScale supports several database types (including Postgres, MySQL, MariaDb and MS SQL Server), which means these can now be utilized within Fly for cacheable workloads.
