100% fail early sounds like the right answer here.

Hi community,

I would like to discuss if we want to fail early for Xcom.set when the value exceeds the storage limit. Otherwise, the database (default xcom backend) truncates the value leading to failure when Xcom reads it, (e.g. on UI, Admin -> Xcoms will also fail).

But I am not sure whether we want to fail the whole task execution if Xcom.set fails and would like to have your inputs.

Thanks,

Ping
