TimescaleDB 2.0 is a new version of the time-series database that sets a new bar for performance, scalability, and cost-effectiveness. It's completely free and built on top of PostgreSQL. The database is designed to handle large volumes of time-series data, allowing developers to focus on their core applications and make better data-driven decisions faster. With its distributed hypertable feature, TimescaleDB can scale up to petabyte-sized datasets and ingest millions of metrics per second. The new version includes improved continuous aggregates, user-defined actions, and informational views. It's available for self-managed installations and will be available on hosted time-series services soon. Developers can migrate from existing software users by following detailed documentation. The database has become the largest developer community for time-series data, with tens of millions of downloads and over 500,000 active databases.
