TimescaleDB is an open-source PostgreSQL extension that improves query performance by up to 1000x, reduces storage utilization by 90%, and provides features essential for time-series and analytical applications. It enables developers to build on top of PostgreSQL and "future-proof" their applications. With TimescaleDB, developers can benefit from a library of over 100 hyperfunctions that make complex time-series analysis easy using SQL, as well as a built-in job scheduling engine for setting up automated workflows. The extension also provides features like compression, continuous aggregates, data retention policies, and declarative partitioning, which help to improve performance and reduce storage costs. By harnessing the power of PostgreSQL's extension framework, TimescaleDB supercharges PostgreSQL for time-series and analytical applications, providing a better developer experience while maintaining 100% compatibility with PostgreSQL.
