Atlas Charts has added support for serverless instances and online archive data sources, allowing users to visualize two new sources of data in their visualizations. Serverless instances provide scalable resource usage without upfront provisioning costs, while online archives enable automated data tiering to optimize storage and costs. These new data sources are now natively available for visualization with zero ETL, making it easier for users to create custom dashboards and charts. The updated feature supports all cluster configurations in Atlas, offering more flexibility and control for project owners.
