I have a couple of loosely related comments: - At a very high level, what information are you attempting to report to sentry with this breadcrumb? At first glance it seems that this is attempting to report the status of this task instance's dependencies, but I am not sure that this is particularly informative as a TI will not be run if its dependencies are unmet. - How are these breadcrumbs reconciled with specific task instances? I can't seem to find any kind of scope or context linking them together. (this is basically the same question as https://github.com/apache/airflow/pull/5407#discussion_r297693203) - Do you think it could be helpful to pass more TI data to sentry by using the breadcrumbs `data` field? - I could see some value in reporting data about *all* TIs in a DagRun (not just this specific TI's direct parents), for instance this could help users investigate race conditions between parallel tasks. WDYT? - I think you may be able to refactor `get_task_instance` into `get_task_instances`; if you make the function accept a list of tasks and return a list of TIs you could move it outside the loop in `sentry.py:132` which would reduce the number of calls to the database. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
