Connect to Your Data
You can connect to and access data from a variety of sources, including lakehouse catalogs, object storage, and databases. These sources are supported across Dremio projects, providing a unified foundation for data exploration and analytics.
Catalogs
Every Dremio project includes a native Open Catalog, powered by Apache Polaris. You can connect additional Open Catalogs from other projects and the following external catalogs:
Object Storage
Dremio supports Amazon S3 and Azure Storage as object storage services.
Databases
You can run queries directly on the data in databases, which are referred to as external sources. In addition, you can run external queries:
- That use the native syntax of the relational database.
- To process SQL statements that are not supported by Dremio or are too complex to convert.
Network Connectivity
When connecting Dremio to data sources, the connection must use public networking. Ensure that the data source endpoint is publicly accessible and that network egress rules, firewall settings, and IAM permissions are properly configured to allow outbound connectivity from Dremio to the source.
