​
Prerequisites

  • Appropriate permission: nx1-tenant-admin,nx1_catalog_admin, nx1_s3_admin, ranger-admin, superset_user, spark_sql, and trino_admin
  • A previously ingested dataset

Create a data shares credential in a provider tenant

Perform these steps to create a data shares credential.
  1. Log in to NexusOne in the provider tenant.
  2. On the top navigation bar, hover your mouse over Govern and then select Data Shares Credential.
  3. Click the plus sign to create a client.
  4. In the Client Name field, enter a client name and then click Create. NexusOne appends gravitino-shared to the client’s name.

Access datasets in a provider tenant from a consumer tenant

To access datasets in a provider tenant from a consumer tenant, you must configure a catalog in the consumer tenant. Perform these steps to configure the catalog.
  1. Log in to NexusOne in the consumer tenant.
  2. On the top navigation bar, hover your mouse over Govern, and then select Catalogs.
  3. Click the plus sign to create a catalog.
  4. In the Name field, enter a catalog name.
  5. For the Catalog Type, select Iceberg.
  6. Configure the connection by entering values for the following key fields:
    • iceberg.catalog.type
    • iceberg.rest-catalog.uri
    • iceberg.rest-catalog.oauth2.credential
    • iceberg.rest-catalog.oauth2.server-uri
    • iceberg.rest-catalog.vended-credentials-enabled
  7. Click Create.
Once the consumer tenant saves the catalog configuration, the NexusOne platform automatically provisions this new shared catalog. NexusOne then attaches this shared catalog to the consumer tenant’s Spark and Trino data processing engines. Afterward, the shared catalog becomes immediately visible and ready so you can use it in a query workload or in NexusOne portal features, such as Ask or Quality.
