  • Added 5 retries to extract_xcom to guard against intermittent network connectivity failures.
  • xcom json is validated to make sure entire json was retrieved. If json validation fails extract_xcom keeps on retrying.
  • Finally xcom sidecar container is killed after either extract_xcom retry limit is reached or if valid json could be retrieved.
  • Also added 5 retries to extract_xcom_kill method as well to guard against intermittent network connectivity failures.

closes: #32111

Congratulations on your first Pull Request and welcome to the Apache Airflow community! If you have any issues or are unsure about any anything please check our Contribution Guide (https://github.com/apache/airflow/blob/main/CONTRIBUTING.rst)
Here are some useful points:

  • Pay attention to the quality of your code (ruff, mypy and type annotations). Our pre-commits will help you with that.
  • In case of a new feature add useful documentation (in docstrings or in docs/ directory). Adding a new operator? Check this short guide Consider adding an example DAG that shows how users should use it.
  • Consider using Breeze environment for testing locally, it's a heavy docker but it ships with a working Airflow and a lot of integrations.
  • Be patient and persistent. It might take some time to get a review or get the final approval from Committers.
  • Please follow ASF Code of Conduct for all communication including (but not limited to) comments on Pull Requests, Mailing list and Slack.

Isn't the description / intenti different now? In the description you write about killing the xcom container only on failure, but seems it is killed always ?

Took a bit of time re-reading the code and first wanted to complain - because the json.loads() looked use-less first hand for me.
PR looks good but still I'd prefer to keep a small additional comment for somebody in future w/o PR context to better understand the logic.
