Thanks @<1523701435869433856:profile|SmugDolphin23> , tho are you sure I don't need to override the deserialization function even if I pass multiple distinct objects as a tuple ?

Well at this point I might as well try to write a PR implementing the behavior I described above

Hmm, in that case you might need to write it. Doesn’t hurt trying eitherway

That would be much appreciated

Hi @<1523702000586330112:profile|FierceHamster54> ! This is currently not possible, but I have a workaround in mind. You could use the artifact_serialization_function parameter in your pipeline. The function should return a bytes stream of the zipped content of your data with whichever compression level you have in mind.
If I'm not mistaken, you wouldn't even need to write a deserialization function in your case, because we should be able to unzip your data just fine.
Wdyt?
