[GitHub] [airflow] ashb edited a comment on pull request #12858: Store per-task TIDeps in serialized blob

   The space saving is mainly for extreme cases (such as 22k tasks in one dag) but size also affects deserialization time - when I want milliseconds to matter :)
   
   The main requirement here is to not blindly inflate a class name from the JSON as that poses a security risk (long term, if not now) - instead we should lookup the class in a pre-registered list like we do for operator links.
   
   I had hoped to get this done properly for 2.0.0 but ran out of time, and decided that it was better to release than delay for this improvement
