   You mean using the "conf" attribute of the DagRun ?
   
   That would indeed be an option I suppose, but :
   
   * `conf` is stored as `PickleType`, which is good if you need to pass any kind of Python object to the DagRun, but not suitable at all for external use such as SQL Query
   * from my understanding,  `conf` should be considered as the input values for the DagRun, and as such should not be tampered with during dag execution. Of course you can do it but input values should probably be immutable and that kind of metadata would be better off stored another place.
