I have a ci-cd deployment process which sets my automation to run, we have a table which have release id and run status and I am checking it's status if it is run then i am continuing the tests, which is not "run" then I am blocking the pytest_collection_finish process but since i am using xdist and have 40 nodes, it sends requests to db for all nodes and i couldn't find a method for just blocking the execution only for master and hold the nodes to start. Simply it will help me to reduces collection and machine preparations time
