Once you have configured the Trino user permissions, you can establish a connection between Atlan and Trino.

To crawl metadata from Trino, complete the following steps.

Select the source

To select Trino as your source:

In the top right of any screen, navigate to New and then click New Workflow.
From the list of packages, select Trino Assets and click on Setup Workflow.

To enter your Trino credentials:

For Host enter the host for your Trino instance.
For Port enter the port of your Trino instance.
For Username enter the name of the user you created.
For Password enter the password for the user you created.
Click Test Authentication to confirm connectivity to Trino using these details.
When successful, at the bottom of the screen click Next.

To complete the Trino connection configuration:

Provide a Connection Name that represents your source environment. For example, you might use values like production, development, gold, or analytics.
(Optional) To change the users able to manage this connection, change the users or groups listed under Connection Admins.
🚨 Careful! If you do not specify any user or group, nobody will be able to manage the connection — not even admins.
At the bottom of the screen, click Next to proceed.

Before running the Trino crawler, you can further configure it.

You can override the defaults for any of these options:

Select the Trino assets you want to exclude from crawling in the Exclude Metadata field. (This will default to no assets, if none are specified.)
Select the Trino assets you want to include in crawling in the Include Metadata field. (This will default to all assets, if none are specified.)

💪 Did you know? If an asset appears in both the include and exclude filters, the exclude filter takes precedence.

To run the Trino crawler, after completing the steps above:

To run the crawler once, immediately, at the bottom of the screen click the Run button.
To schedule the crawler to run hourly, daily, weekly or monthly, at the bottom of the screen click the Schedule & Run button.

Once the crawler has completed running, you will see the assets in Atlan's asset page! 🎉
