API Reference
For information on the relationship of the Dremio Cloud entities, see the object model topic.
API Endpoint
To use Dremio Cloud APIs, use the endpoint for your control plane.
US Control Planehttps://api.dremio.cloud/v0/
https://api.eu.dremio.cloud/v0/
Authentication
The Dremio API requires authentication with a personal access token (PAT). PATs are created in the Dremio UI. Follow the instructions in Creating a PAT to get a PAT to use in API requests.
API requests must use the Authorization header. The header's value must specify the Bearer type followed by a space and the PAT: Bearer {PAT}. This example request to retrieve a catalog demonstrates how to use a PAT in an API request:
curl -X GET 'https://api.dremio.cloud/v0/projects/48ca6975-39ad-47cb-9bb5-de73060380f6/catalog' \
--header 'Authorization: Bearer dJhGBUDAVv+9Wlsp/I/o/87Vq+omuvpC/YEy6U25S79i74KhD2W6q2sr44emKy==' \
--header 'Content-Type: application/json'
Idempotent Requests
Idempotence is an operation or a service call that produces the same result when it is called multiple times.
API endpoints support idempotency to safely retry user requests without performing a duplicate operation. This is helpful when an API request is interrupted in transit and a response is not received. In such cases, you can retry that request with the same idempotency key to ensure that there is no duplicate request.
To create an idempotent request, add a requestId parameter to the request. The value is a unique generated UUID. The server uses the idempotency key to identify consequent retries of the same API request.
Only POST operations accept the idempotency key.
To get a successful POST response for entities, you must add the requestId parameter in the corresponding POST request.
Adding idempotent keys in PUT, GET, and DELETE operations creates no impact as they are idempotent.
An idempotent key can be reused after 24 hours in a new POST operation.
Query Parameters
Dremio supports query parameters for many API endpoints. The documentation for each API lists the supported query parameters for specific endpoints, along with any default and maximum values for the query parameters.
pageToken Query Parameter
For endpoints that support the pageToken query parameter, responses will include a page token if the Dremio instance has more results than the maximum per page. Use the value for this token in your request URL as the pageToken value to retrieve the next page of results.
As an example, the reflection summary endpoint supports the pageToken parameter. If the reflection summary contains more than 50 results, the response will include the nextPageToken attribute. To retrieve the next 50 results, add ?pageToken={nextPageToken_value} to the request URL:
curl -X GET 'https://api.dremio.cloud/v0/api/projects/{project-id}/reflection-summary?pageToken=BhQxNjc0MjhlYi03OTM2LTRlYTItYTFmYi0yM2IxYWM2ZTk0NTQSAA==' \
--header 'Authorization: Bearer <PersonalAccessToken>' \
--header 'Content-Type: application/json'
For subsequent requests, replace the pageToken value in the request URL with the token value from the previous response. If the response does not include a token attribute and value, you have retrieved the last page of available results.
Do not change any other query parameters included in the request URL when you use pageToken.
maxResults Query Parameter
Use the maxResults query parameter to specify the maximum number of results to retrieve in each request.
For example, if you want to retrieve no more than 25 results for an endpoint that supports the maxResults query parameter, append ?maxResults=25 to the request URL:
curl -X GET 'https://api.dremio.cloud/v0/api/projects/{project-id}/reflection-summary?maxResults=25' \
--header 'Authorization: Bearer <PersonalAccessToken>' \
--header 'Content-Type: application/json'
filter Query Parameter
Use the filter query parameter to filter responses so that they include only results with the specified attributes and values. The value for the filter query parameter is a URL-encoded JSON string that represents a JSON object that specifies the desired attributes and values.
As an example, the reflection summary endpoint supports the filter query parameter for certain specific attributes. To retrieve only the raw reflections that are refreshed manually or by schedule, are enabled, and apply to datasets with samples.dremio.com in their paths, the filter JSON object would look like this:
{
"reflectionType": ["RAW"],
"refreshStatus": ["MANUAL","SCHEDULED"],
"enabledFlag": true,
"reflectionNameOrDatasetPath": "samples.dremio.com"
}
To use the JSON object as the filter value, convert it to URL-encoded JSON and add it to the request URL:
curl -X GET 'https://api.dremio.cloud/v0/api/projects/{project-id}/reflection-summary?filter=%7B%0A%20%20%22reflectionType%22%3A%20%5B%22RAW%22%5D%2C%0A%20%20%22refreshStatus%22%3A%20%5B%22MANUAL%22%2C%22SCHEDULED%22%5D%2C%0A%20%20%22enabledFlag%22%3A%20true%2C%0A%20%20%22reflectionNameOrDatasetPath%22%3A%20%22samples.dremio.com%22%0A%7D' \
--header 'Authorization: Bearer <PersonalAccessToken>' \
--header 'Content-Type: application/json'
Read the endpoint-specific documentation to learn which attributes each endpoint supports for the filter query parameter.
view Query Parameter
Use the view query parameter to specify the level of detail to include in the response.
For example, the Arctic Catalog endpoint for retrieving all jobs supports retrieving SUMMARY or FULL level of detail in the response. To retrieve jobs with FULL detail:
curl -X GET 'https://api.dremio.cloud/v0/api/arctic/catalogs/{catalogId}/jobs?view=FULL' \
--header 'Authorization: Bearer <PersonalAccessToken>' \
--header 'Content-Type: application/json'
Read the endpoint-specific documentation to learn which attributes each endpoint supports for the view query parameter.
limit and offset Query Parameters
The limit query parameter allows you to retrieve a specific number of results. For endpoints that support the limit query parameter, you can specify the number of results to retrieve. For example, if you only want to retrieve the first 10 available results, add ?limit=10 to the request URL:
curl -X GET 'https://api.dremio.cloud/v0/projects/{project-id}/job/{id}/results?limit=10' \
--header 'Authorization: Bearer <PersonalAccessToken>' \
--header 'Content-Type: application/json'
The offset query parameter allows you to skip a specific number of results in the response. When a response contains many results, you can use the limit and offset query parameters together to break the response into pages.
For example, consider a job result response object that contains 5000 results. The Job API allows you to retrieve a maximum of 500 results per request. To retrieve all 5000 results, start by adding ?limit=500 to the request URL to retrieve the first 500:
curl -X GET 'https://api.dremio.cloud/v0/projects/{project-id}/job/{id}/results?limit=500' \
--header 'Authorization: Bearer <PersonalAccessToken>' \
--header 'Content-Type: application/json'
In the next request, to retrieve the next 500 results (rows 501-1000), add &offset=500 to the request URL:
curl -X GET 'https://api.dremio.cloud/v0/projects/{project-id}/job/{id}/results?limit=500&offset=500' \
--header 'Authorization: Bearer <PersonalAccessToken>' \
--header 'Content-Type: application/json'
To retrieve the next 500 results (rows 1001-1500), increment the offset parameter to 1000 in the next request:
curl -X GET 'https://api.dremio.cloud/v0/projects/{project-id}/job/{id}/results?limit=500&offset=1000' \
--header 'Authorization: Bearer <PersonalAccessToken>' \
--header 'Content-Type: application/json'
Continue incrementing the offset parameter in requests until you have retrieved all 5000 results.
type Query Parameter
Use the type query parameter to limit your request so that the response includes only results for the type you specify.
For example, if an endpoint supports the type query parameter, and the endpoint's list of valid values includes SOURCE, you can limit the response so that it includes only results for sources. Append ?type=SOURCE to the request URL:
curl -X GET 'https://https://api.dremio.cloud/v0/projects/{project-id}/catalog/privileges?type=SOURCE' \
--header 'Authorization: Bearer <PersonalAccessToken>' \
--header 'Content-Type: application/json'
Read the documentation for each API to learn about endpoint-specific support for the type query parameter, including lists of valid values.
include and exclude Query Parameters
The include query parameter allows you to return the name of a non-default response field. You can retrieve either a list of access control list names - aclNames - or a list of permissions.
curl -X GET 'https://api.dremio.cloud/v0/projects/{project-id}/catalog/ffbe8c1d-1db7-48d1-9c58-f452838fedc0?include=permissions' \
--header 'Authorization: Bearer <PersonalAccessToken>' \
--header 'Content-Type: application/json'
The exclude query parameter allows you to exclude the children field from the response.
curl -X GET 'https://api.dremio.cloud/v0/projects/{project-id}/catalog/ffbe8c1d-1db7-48d1-9c58-f452838fedc0?exclude=children' \
--header 'Authorization: Bearer <PersonalAccessToken>' \
--header 'Content-Type: application/json'
orderBy Query Parameter
Use the orderBy query parameter to organize the response in ascending or descending order based on the value of the specified attribute. The default is ascending order. To specify descending order, add a - character before the attribute name.
For example, the reflection summary endpoint supports ordering the response by reflectionName, datasetName, or reflectionType. To organize the response in ascending order by reflectionName:
Example Request With orderBy Query Parameter (Ascending Order)curl -X GET 'https://api.dremio.cloud/v0/api/projects/{project-id}/reflection-summary?orderBy=reflectionName' \
--header 'Authorization: Bearer <PersonalAccessToken>' \
--header 'Content-Type: application/json'
To organize the response in descending order, add a - before the attribute name:
curl -X GET 'https://api.dremio.cloud/v0/api/projects/{project-id}/reflection-summary?orderBy=-reflectionName' \
--header 'Authorization: Bearer <PersonalAccessToken>' \
--header 'Content-Type: application/json'
Read the endpoint-specific documentation to learn which attributes each endpoint supports for the orderBy query parameter.
