dbt Data Freshness
Mode’s dbt integration allows users to view metadata about data freshness from dbt directly in Mode reports. The integration allows Mode users to present information about when source data was last refreshed for a report, by mapping the tables used in the report to dbt models.
Connect Mode to dbt
dbt Cloud Requirements
- Be on a paid plan (Team or Enterprise) of dbt Cloud
- Have freshness configured for relevant sources
- Add a
dbt source snapshot-freshnessstep to the job you want to get metadata for in Mode. See dbt documentation for more detail.
- Update to at least v.0.18.1 of dbt Core
In order to set up dbt data freshness in Mode, you will need to have:
Job IDfor the dbt Job that updates your production data
Service Account Tokengenerated from dbt’s metadata API
Get dbt Job ID
A job in dbt represents the deployment of a dbt project on a schedule. It is common for organizations to have multiple dbt Cloud jobs, so you should choose the job that serves as the primary mechanism for updating your production data. This job must also have freshness checks configured for relevant sources to surface data freshness in Mode.
NOTE: You will not be able to surface dbt data freshness in Mode if freshness is configured in a job separate from your production job.
To get the Job ID, open up your dbt Cloud account and navigate to the Jobs tab. From there, you can copy the ID from the URL.
Generate a Metadata-Only Service Account Token
Mode uses dbt’s Metadata API to pull data freshness information from dbt jobs into Mode Reports. In order to authorize the API, you will need to generate a token in dbt.
To generate a Metadata-only Service Account Token, go to the Account Settings view of dbt Cloud. From there, click on the Service Account tokens page. Create a new Metadata Only token and save.
You will also need to enable the Metadata API to allow querying with the Metadata Only Token. Navigate to the Metadata page in Account Settings to enable access to the API.
For more information on how to generate a Service Account Token, see the dbt Cloud documentation.
Set up in Mode Connection Settings
Once you have a job ID and signature, go to your Workspace’s
Settingsand navigate to the
Manage Connectionstab. Select the Connection you want to enable dbt for and navigate to the
Only Admins or users with permission to manage the Connection will be able to enable the dbt integration. If you have multiple Connections, the integration must be set up for each Connection separately.
Viewing dbt data freshness in Mode Reports
Freshness information from dbt is surfaced on Reports in two places:
- Main Report view
- Report Details
From a Report, you can find when the source data from dbt was last refreshed by clicking on the info icon. In addition to seeing the
Source data last refreshedtime from dbt, you’ll find additional information about the Report, such as when it was last successfully run and last edited.
TIP: Compare the dbt
Source data last refreshedtime to the Report’s
Last successful runtime to see if the Report you’re viewing is up to date. If the source data was last refreshed more recently than the Report was run, you may see fresher data in the Report by clicking the
To view the
Source data last refreshedtime for each table included in the Report, go to Report Details. A particular table can have multiple parent source models in dbt. The timestamp shown is the last updated time for the oldest dbt source model. Hover over the timestamp to see the dbt source name.
If a Report’s queries reference Connections that don’t have dbt enabled, the table will not be shown in this list.
If Mode is unable to connect to dbt or unable to map any tables in the Report to corresponding dbt models, an error will be shown.
If some tables do not have a freshness timestamp, they will be surfaced in Report Details, with the message
No models found in dbt. This may happen if the table contains only historical data and none of its sources has freshness checks configured, or if the table is not modeled in dbt (i.e. raw data).
If I have multiple dbt jobs, which job ID should I add to Mode?
A job in dbt represents the deployment of a dbt project on a schedule. It is common for organizations to have multiple dbt Cloud jobs, so they should choose the job that serves as the primary mechanism for updating production data. This job must also have freshness checks configured for relevant sources to surface data freshness in Mode.
Where does “source data last refreshed” timestamp come from?
The timestamp considers all tables in the Report from a Connection that has dbt enabled. Those tables are mapped to dbt models, for which we get the oldest source model’s last loaded at time.
What if I create a report using one dbt-enabled Connection and another Connection that does not have dbt enabled?
The freshness timestamp will simply ignore the tables from that Connection. The tables from the Connection without dbt enabled will not be shown in Report Details. No errors will be displayed.
Why is the Source data last refreshed value slightly different in the Report header than in View Details?
This sometimes happens if you have left a Report open. Refreshing the Report will surface the most up to date timestamp for data freshness from dbt.
What does “Data unavailable” mean?
This error will only be shown if no timestamp can be shown in Report Activity. This may be due to:
An issue connecting with dbt’s API (i.e. bad credentials) Tables not having corresponding dbt models
What does “no models found in dbt” mean?
Timestamps may not be shown if we can’t map a Mode table back to a dbt model. This usually happens if the table is not modeled in dbt (i.e. raw data).
The tables with “data unavailable” messaging will
notbe shown if the Connection does not have dbt enabled. Only tables from Connections that have dbt enabled will be shown in the list or count toward error messaging.
