Iceberg / Delta

Open table formats on object storage.

At a glance

Setup

1. Open Connect source

   In the app, go to Data sources and choose Connect source. Open the Data lakes tab and select Iceberg / Delta.

2. Enter connection details

   Provide the host, database name, and a read-only user and password. Enable SSL/TLS if your database requires it, or configure an SSH tunnel for a private network.

3. Save the connection

   Queringo tests the connection before saving, then discovers the schema. PII is flagged and masked by default during discovery.

Where to find these in your provider

1. Confirm your tables are written in Iceberg or Delta format on S3, ADLS Gen2, or GCS.
2. Provide an access principal (IAM user/role or service principal) with read access to the bucket and the catalog metadata.
3. Paste the catalog endpoint (Glue, Hive Metastore, or REST catalog), the bucket, and the credentials into the connection form.

Test the connection

Queringo runs a connection test as part of saving. If it fails, the error message indicates what to check (credentials, network reachability, or scope). From Data sources, you can re-run Test connection on the source row any time, for example after rotating a secret or changing network rules.

Edit or rotate

To change connection details (host, port, or database), open the source from Data sources and edit it. To swap only the secret (password, key file, or token), use Rotate credentials so existing dashboards and alerts keep working. See Rotating credentials.
