Snowflake miner package¶
The Snowflake miner package mines query history from Snowflake. This data is used for generating lineage and usage metrics.
Source extraction¶
To mine query history directly from Snowflake using its built-in database:

- Base configuration for a new Snowflake miner.
- You must provide the exact
qualifiedName
of the Snowflake connection in Atlan for which you want to mine query history. -
To create a workflow for mining history directly from Snowflake using its built-in database you need to provide:
- name of the database to extract from.
- name of the schema to extract from.
- date and time from which to start mining, as an epoch.
-
Optionally, you can specify list of users who should be excluded when calculating usage metrics for assets (for example, system accounts).
- Optionally, you can specify whether to enable native lineage from Snowflake,
using Snowflake's
ACCESS_HISTORY.OBJECTS_MODIFIED
Column.Note:
this is only available only for Snowflake Enterprise customers. - Build the minimal package object.
- Now, you can convert the package into a
Workflow
object. -
Run the workflow by invoking the
run()
method on the workflow client, passing the created object.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.

Re-run existing workflow¶
To re-run an existing workflow for Snowflake query mining:
Re-run existing Snowflake workflow | |
---|---|

|
- You can search for existing workflows through the
WorkflowSearchRequest
class. - 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 theSnowflakeMiner
. (You can also specify the maximum number of resulting workflows you want to retrieve as results.) -
Once you've found the workflow you want to re-run, you can simply call the
rerun()
helper method on the workflow search result. TheWorkflowRunResponse
is just a subtype ofWorkflowResponse
so has the same helper method to monitor progress of the workflow run.- Optionally, you can use the
rerun(true)
method with idempotency to avoid re-running a workflow that is already in running or in a pending state. This will return details of the already running workflow if found, and by default, it is set tofalse
Workflows run asynchronously

Searching by the
atlan-snowflake-miner
prefix will ensure you only find existing Snowflake miner 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.)
POST /api/service/workflows/submit | |

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