[GitHub] [beam] kennknowles opened a new issue, #18518: PubSub subscriptions automatically created in Python DirectRunner not reliably cleaned up

kennknowles opened a new issue, #18518:
URL: https://github.com/apache/beam/issues/18518

   In the Python DirectRunner, we attempt to garbage-collect automatically-created PubSub subscriptions here (https://github.com/apache/beam/blob/446f311746b74bdfb420ba71d76097d683fde9a1/sdks/python/apache_beam/runners/direct/transform_evaluator.py#L370).  However, this mechanism may not succeed, since it is called on the __del__ method when other references may have already been garbage-collected.  We should further investigate the mechanism here and attempt to make it more reliable.
