dbt assets package

The dbt assets package crawls dbt assets and publishes them to Atlan for discovery.

Multi-tenant cloud

Will create a new connection

This should only be used to create the workflow the first time. Each time you run this method it will create a new connection and new assets within that connection — which could lead to duplicate assets if you run the workflow this way multiple times with the same settings.

Instead, when you want to re-crawl assets, re-run the existing workflow (see Re-run existing workflow below).

1.0.0

To create a new crawl of dbt assets from a multi-tenant dbt Cloud account:

Java Python Raw REST API

Workflow dbt = DbtCrawler.mtCloudAuth( // (1)
                "dbt-snowflake", // (2)
                "dbts_tlspokm3iSWCsNJw4l1kBsGwSvBMTDMRjKzTuaYnjsYNCGnBYTtJDx4D==", // (3)
                List.of(RoleCache.getIdForName("$admin")), // (4)
                null,
                null,
                "{\"24670\":{\"211208\":{\"163013\":{\"207502\":{}}}}}", // (5)
                null, // (6)
                null); // (7)
WorkflowResponse response = dbt.run(); // (8)

1. The DbtCrawler package will create a workflow to crawl dbt assets. The mtCloudAuth() method creates a workflow for crawling assets from a multi-tenant dbt Cloud account.
2. You must provide a name for the connection that the dbt assets will exist within.
3. You must provide the service account token for your dbt Cloud account.

4. You must specify at least one connection admin, either:

   • everyone in a role (in this example, all $admin users)
   • a list of groups (names) that will be connection admins
   • a list of users (names) that will be connection admins

5. You can also optionally specify the list of assets to include in crawling. This is a highly-nested map structure of numeric IDs for the account, project, etc. You will almost certainly need to set up the filter you want through the UI first, and look at the developer console of your browser to see the structure. (If set to null, all assets will be crawled.)

6. You can also optionally specify the list of assets to exclude from crawling. This follows the same structure as the inclusion filter. (If set to null, no assets will be excluded.)
7. You can also optionally specify the qualifiedName of a connection to a source (such as Snowflake), to limit the crawling of dbt assets to that existing connection in Atlan.

8. You can then run the workflow using the run() method on the object you've created.

   Workflows run asynchronously

   Remember that workflows run asynchronously. See the packages and workflows introduction for details on how you can check the status and wait until the workflow has been completed.

Create the workflow via UI only

We recommend creating the workflow only via the UI. To rerun an existing workflow, see the steps below.

Re-run existing workflow

1.0.0

To re-run an existing workflow for dbt assets:

Java Python Raw REST API

List<WorkflowSearchResult> existing = WorkflowSearchRequest // (1)
            .findByType(DbtCrawler.PREFIX, 5); // (2)
// Determine which of the results is the dbt workflow you want to re-run...
WorkflowRunResponse response = existing.get(n).rerun(); // (3)

1. You can search for existing workflows through the WorkflowSearchRequest class.
2. You can find workflows by their type using the findByType() helper method and providing the prefix for one of the packages. In this example, we do so for the DbtCrawler. (You can also specify the maximum number of resulting workflows you want to retrieve as results.)

3. Once you've found the workflow you want to re-run, you can simply call the rerun() helper method on the workflow search result. The WorkflowRunResponse is just a subtype of WorkflowResponse so has the same helper method to monitor progress of the workflow run.

   Remember that workflows run asynchronously. See the packages and workflows introduction for details on how you can check the status and wait until the workflow has been completed.

Coming soon

Requires multiple steps through the raw REST API

1. Find the existing workflow.
2. Send through the resulting re-run request.

{
  "from": 0,
  "size": 5,
  "query": {
    "bool": {
      "filter": [
        {
          "nested": {
            "path": "metadata",
            "query": {
              "prefix": {
                "metadata.name.keyword": {
                  "value": "atlan-dbt" // (1)
                }
              }
            }
          }
        }
      ]
    }
  },
  "sort": [
    {
      "metadata.creationTimestamp": {
        "nested": {
          "path": "metadata"
        },
        "order": "desc"
      }
    }
  ],
  "track_total_hits": true
}

1. Searching by the atlan-dbt prefix will ensure you only find existing dbt assets workflows.

   Name of the workflow

   The name of the workflow will be nested within the _source.metadata.name property of the response object. (Remember since this is a search, there could be multiple results, so you may want to use the other details in each result to determine which workflow you really want.)

{
  "namespace": "default",
  "resourceKind": "WorkflowTemplate",
  "resourceName": "atlan-dbt-1684500411" // (1)
}

1. Send the name of the workflow as the resourceName to rerun it.
