   Hi @shahar1,
   I have a concern about this implementation.
   Since the `XCom` has a hard limit to 1GB (due to the DB field type `JSONB`) 
and the return value from a Operator stored in the `XCom`, do we need to do 
something extra? I know the 1GB is a huge size but still... 
   
   Lets assume you are migration a bucket to another bucket (this can be 
trained AI model data) and try to move the data between buckets. I think we can 
hit that limit in this kind of scenario
