The folderPath and fileName properties capture the location of the new blob. csv is created in the folder event-testing in the container sample-data. In the preceding example, the trigger is configured to fire when a blob path ending in. For detailed explanation, see Reference Trigger Metadata in Pipelines After mapping the properties to parameters, you can access the values captured by the trigger through the expression throughout the pipeline. The storage event trigger captures the folder path and file name of the blob into the properties and To use the values of these properties in a pipeline, you must map the properties to pipeline parameters. If your pipeline has parameters, you can specify them on the trigger runs parameter side nav. Click Next: Data preview to confirm the configuration is correct and then Next to validate the Data preview is correct. dropdown and select the trigger you created. When the side nav appears, click on the Choose trigger. To attach a pipeline to this trigger, go to the pipeline canvas and click Trigger and select New/Edit. Once your filter conditions have been verified, click Finish. Configuring filters that are too broad can match a large number of files created/deleted and may significantly impact your cost. This screen shows the existing blobs matched by your storage event trigger configuration. Select whether or not your trigger ignores blobs with zero bytes.Īfter you configure you trigger, click on Next: Data preview.
In your specified storage location, each event will trigger the Data Factory and Synapse pipelines associated with the trigger. Select whether your trigger will respond to a Blob created event, Blob deleted event, or both. Other types of wildcard matching aren't supported for the trigger type.
Container and folder names, when specified, they must be separated by a /blobs/ segment. Blob path ends with: The blob path must end with a file name or extension.
This field can't be selected if a container isn't selected. Valid values include 2018/ and 2018/april/shoes.csv. Blob path begins with: The blob path must start with a folder path.You can use variety of patterns for both Blob path begins with and Blob path ends with properties, as shown in the examples later in this article. Your storage event trigger requires at least one of these properties to be defined. The Blob path begins with and Blob path ends with properties allow you to specify the containers, folders, and blob names for which you want to receive events. For more information about access control, see Role based access control section. No additional permission is required: Service Principal for the Azure Data Factory and Azure Synapse does not need special permission to either the Storage account or Event Grid. To create a new or modify an existing Storage Event Trigger, the Azure account used to log into the service and publish the storage event trigger must have appropriate role based access control (Azure RBAC) permission on the storage account.
