Late Span finish example.
|
|
=========================
|
|
|
|
This example shows a ``Span`` for a top-level operation, with independent, unknown lifetime, acting as parent of a few asynchronous subtasks (which must re-activate it but not finish it).
|
|
|
|
.. code-block:: python
|
|
|
|
# Fire away a few subtasks, passing a parent Span whose lifetime
|
|
# is not tied at all to the children.
|
|
def submit_subtasks(self, parent_span):
|
|
def task(name, interval):
|
|
with self.tracer.scope_manager.activate(parent_span, False):
|
|
with self.tracer.start_active_span(name):
|
|
time.sleep(interval)
|
|
|
|
self.executor.submit(task, "task1", 0.1)
|
|
self.executor.submit(task, "task2", 0.3)
