How to maintain order of execution of listeners in case of multiple listeners

[mishrasangeeta87]

Hello,

I have installed openlineage plugin which uses listener feature OpenLineage Integration Airflow . I also want to add my own listener. So in this case how do we control the order of execution. Say if I want openlineage listener code to execute first and then want my listener plugin to execute during the events, is it possible?

@mishrasangeeta87 I know this: https://pluggy.readthedocs.io/en/latest/#call-time-order

And pytest-dev/pluggy#250

So, I haven't tried it, but marking your hookimpl with

    @hookimpl(trylast=True)

should work in this case.

In general, we don't have ordering mechanism for plugins other than this in Airflow.
If we needed it, it could be done - by controlling order in which plugins are registered, instead of doing it eagerly.
