Catalog

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.

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

---

path Array of String

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

Example: ["Testing"]

---

Example: CONTAINER

---

containerType String

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

Enum: SPACE, SOURCE, FOLDER, HOME

Example: SPACE

---

stats Object

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}

---

createdAt String

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

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

---

permissions Array of String

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"]

Attributes of the stats Object

datasetCount Integer

Number of datasets the catalog object contains.

Example: 18

---

datasetCountBounded Boolean

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

Example: false

Retrieving a Catalog
