Hex is built to seamlessly handle cloud-scale workloads. Hex runs queries directly against the customer’s data warehouse, meaning workflows can scale as large as the underlying warehouse allows.

Hex stores all cell output data, including previews of SQL results, in AWS RDS, and uploaded files are stored in AWS S3. Data in RDS and S3 persists indefinitely until the associated project is deleted or a deletion request is made. Caching of SQL cell output data is opt-in, configurable, and stored in S3 for up to 90 days.

Hex supports SSO via OIDC within the product. Hex gives users the tools to implement role-based access control on all Hex artifacts. This gives customers fine-grained control over who in an organization has access to specific data. Administrators have control over what users have access to and can restrict access to databases, and the ability to view or edit projects.
