Trigger Trigger

yaml
type: "io.kestra.plugin.azure.storage.adls.Trigger"

Run a flow as soon as files are uploaded to Azure Data Lake Storage

This trigger will poll the specified Azure Data Lake Storage bucket every interval. Using the from and regExp properties, you can define which files arrival will trigger the flow. Under the hood, we use the Azure Data Lake Storage API to list the files in a specified location and download them to the internal storage and process them with the declared action. You can use the action property to move or delete the files from the container after processing to avoid the trigger to be fired again for the same files during the next polling interval.

Examples

Run a flow if one or more files arrived in the specified Azure Data Lake Storage bucket location. Then, process all files in a for-loop either sequentially or concurrently, depending on the concurrencyLimit property.
