class airflow.providers.amazon.aws.triggers.s3.S3KeyTrigger(bucket_name, bucket_key, wildcard_match=False, aws_conn_id='aws_default', poke_interval=5.0, should_check_fn=False, **hook_params)[source]

Bases: airflow.triggers.base.BaseTrigger

S3KeyTrigger is fired as deferred class with params to run the task in trigger worker.

Parameters

  • bucket_name (str) – Name of the S3 bucket. Only needed when bucket_key is not provided as a full s3:// url.

  • bucket_key (str | list[str]) – The key being waited on. Supports full s3:// style url or relative path from root level. When it’s specified as a full s3:// url, please leave bucket_name as None.

  • wildcard_match (bool) – whether the bucket_key should be interpreted as a Unix wildcard pattern

  • aws_conn_id (str) – reference to the s3 connection

  • hook_params (Any) – params for hook its optional

class airflow.providers.amazon.aws.triggers.s3.S3KeysUnchangedTrigger(bucket_name, prefix, inactivity_period=60 * 60, min_objects=1, inactivity_seconds=0, previous_objects=None, allow_delete=True, aws_conn_id='aws_default', last_activity_time=None, verify=None, **hook_params)[source]

Bases: airflow.triggers.base.BaseTrigger

S3KeysUnchangedTrigger is fired as deferred class with params to run the task in trigger worker.

Parameters

  • bucket_name (str) – Name of the S3 bucket. Only needed when bucket_key is not provided as a full s3:// url.

  • prefix (str) – The prefix being waited on. Relative path from bucket root level.

  • inactivity_period (float) – The total seconds of inactivity to designate keys unchanged. Note, this mechanism is not real time and this operator may not return until a poke_interval after this period has passed with no additional objects sensed.

  • min_objects (int) – The minimum number of objects needed for keys unchanged sensor to be considered valid.

  • inactivity_seconds (int) – reference to the seconds of inactivity

  • previous_objects (set[str] | None) – The set of object ids found during the last poke.

  • allow_delete (bool) – Should this sensor consider objects being deleted

  • aws_conn_id (str) – reference to the s3 connection

  • last_activity_time (datetime.datetime | None) – last modified or last active time

  • verify (bool | str | None) – Whether or not to verify SSL certificates for S3 connection. By default SSL certificates are verified.

  • hook_params (Any) – params for hook its optional
