Trigger

yaml

type: "io.kestra.plugin.aws.s3.Trigger"

Wait for files on S3 bucket

This trigger will poll every interval s3 bucket. You can search for all files in a bucket 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 bucket (to avoid double detection on new poll)

Examples
