Browse Catalog Content

The catalog content browser lets you explore namespaces, tables, views, schemas, and sample data within any connected Iceberg catalog.

Open the Content Browser​

  1. Navigate to Iceberg > Catalogs
  2. Click on a catalog
  3. Click the Content tab

The browser displays a list of namespaces (databases/schemas) in the catalog.

Browse Namespaces, Tables, and Views​

  • Click a namespace to see its contents
  • Switch between the Tables and Views tabs to list each kind of Iceberg object in the namespace
  • Click a table to view its details

The Views tab is always present. It is empty for catalog backends that do not support Iceberg views — currently AWS Glue and Hadoop catalogs. Hive, JDBC, REST, and Nessie catalogs list views.

View Table Schema​

When you select a table, the browser displays the full Iceberg schema:

  • Column name — the field name
  • Data type — the Iceberg type (string, long, decimal(10,2), timestamp, struct, list, map, etc.)

Complex types (struct, list, map) show their nested field structure.

Preview Sample Data​

The table view includes a data preview showing up to 100 rows of sample data from the table. This is useful for:

  • Verifying that a catalog connection is working correctly
  • Checking that replicated data matches the source
  • Exploring unfamiliar datasets

The preview reads directly from the table's data files — it reflects the current state of the table in storage.

Use Cases​

  • Verify a new catalog — after adding a catalog, open the Content tab to confirm that namespaces and tables are visible
  • Check replication results — open the target catalog's Content tab to verify that replicated tables have the expected schemas and data
  • Find namespace names — browse the catalog before creating scopes, to see the exact (case-sensitive) namespace names
  • Confirm view replication — check the target catalog's Views tab to verify replicated Iceberg views are present
