Catalog API

Use the Catalog API to retrieve and manage sources and spaces as well as the folders, files, tables, and views they contain. The Catalog API also includes endpoints for retrieving lineage information for datasets and for creating and managing tags, wikis, privileges, and grants on catalog objects.

Use the Catalog API endpoint described on this page to retrieve a list of the spaces and sources in your Dremio organization. The response contains the IDs required to make requests to other Catalog API endpoints to create, retrieve, update, and delete objects in your catalog.

Catalog Attributes

List of catalog objects in the Dremio organization.

data

Unique identifier of the catalog object.

Example ed1013cb-4fea-6552-8d43-015215a38bcc

Path of the catalog object within Dremio, expressed as an array.

Example [ "Testing" ]

Unique identifier of the version of the catalog object. Dremio changes the tag whenever the catalog object changes and uses the tag to ensure that PUT requests apply to the most recent version of the catalog object.

Example PR1M7B1Rhjs=

Type of the catalog object. For objects that can contain other catalog objects (the only objects this endpoint retrieves), the type is CONTAINER.

Example CONTAINER

For catalog objects with the type CONTAINER, the type of container.

Enum SPACE , SOURCE , FOLDER , HOME

Example SPACE

Information about the number of datasets in the catalog object and whether the dataset count is bounded. Appears in the response only if the request URL includes the datasetCount query parameter.

Example { "datasetCount": 18, "datasetCountBounded": false }

Date and time that the catalog object was created, in UTC format.

Example 2023-02-14T19:28:40.840Z

Enterprise-only. List of the privileges that you have on the catalog object. Only appears in the response if the request URL includes the permissions query parameter. For more information, read Privileges.

Example [ "READ", "WRITE", "ALTER_REFLECTION", "SELECT", "ALTER", "VIEW_REFLECTION", "MODIFY", "MANAGE_GRANTS", "CREATE_TABLE", "DROP", "EXTERNAL_QUERY", "INSERT", "TRUNCATE", "DELETE", "UPDATE", "EXECUTE", "CREATE_SOURCE", "ALL" ]

stats

Number of datasets the catalog object contains.

Example 18

If the dataset count is bounded, the value is true. Otherwise, the value is false.

Example false

Retrieving a Catalog

Retrieve the catalog for the current Dremio instance.

Method and URL

GET /api/v3/catalog

Parameters

Include a non-default attribute in the response. The available values for the include query parameter are permissions (Enterprise-only) and datasetCount. Specify permissions to include each catalog object's permissions array in the response. Specify datasetCount to include the stats object in the response. For more information, read include and exclude Query Parameters.

Example ?include=permissions

Example Request

curl -X GET 'https://{hostname}/api/v3/catalog' \
--header 'Authorization: _dremio{tokenstring}' \
--header 'Content-Type: application/json'
