schrodinger.seam.testing.stu_tests.preemption_recovery_SIGTERM module

Bases: DoFn

process(_)

Method to use for processing elements.

This is invoked by DoFnRunner for each element of a input PCollection.

The following parameters can be used as default values on process arguments to indicate that a DoFn accepts the corresponding parameters. For example, a DoFn might accept the element and its timestamp with the following signature:

def process(element=DoFn.ElementParam, timestamp=DoFn.TimestampParam):
  ...

The full set of parameters is:

  • DoFn.ElementParam: element to be processed, should not be mutated.

  • DoFn.SideInputParam: a side input that may be used when processing.

  • DoFn.TimestampParam: timestamp of the input element.

  • DoFn.WindowParam: Window the input element belongs to.

  • DoFn.TimerParam: a userstate.RuntimeTimer object defined by the spec of the parameter.

  • DoFn.StateParam: a userstate.RuntimeState object defined by the spec of the parameter.

  • DoFn.KeyParam: key associated with the element.

  • DoFn.RestrictionParam: an iobase.RestrictionTracker will be provided here to allow treatment as a Splittable DoFn. The restriction tracker will be derived from the restriction provider in the parameter.

  • DoFn.WatermarkEstimatorParam: a function that can be used to track output watermark of Splittable DoFn implementations.

  • DoFn.BundleContextParam: allows a shared context manager to be used per bundle

  • DoFn.SetupContextParam: allows a shared context manager to be used per DoFn

Args:

element: The element to be processed *args: side inputs **kwargs: other keyword arguments.

Returns:

An Iterable of output elements or None.

schrodinger.seam.testing.stu_tests.preemption_recovery_SIGTERM.get_worker_clean_log_messages(seam_dir: Path) → list[str]

Return the messages from all worker clean logs, excluding runner and pipeline logs.
