Trigger

yaml

type: "io.kestra.plugin.azure.storage.blob.Trigger"

Wait for files on Azure Blob Storage

This trigger will poll every interval blob storage. You can search for all files in a container or directory in from or you can filter the files with a regExp.The detection is atomic, internally we do a list and interact only with files listed. Once a file is detected, we download the file on internal storage and processed with declared action in order to move or delete the files from the container (to avoid double detection on new poll)

Examples

Wait for a list of file on a Azure Blob Storage bucket and iterate through the files

Interval between polling

The interval between 2 different test of schedule, this can avoid to overload the remote system with too many call. For most of trigger that depend on external system, a minimal interval must be at least PT30S. See ISO_8601 Durations for more information of available interval value
