@ottobackwards Regarding your other question, we mandated that every
message capture the original message and a timestamp as required fields. If
the message doesn't have that, then it fails validation and an error is thrown
for that message.
Certainly after it's parsed, you can apply a stellar transformation and
replace the timestamp field with another one using Stellar.
There is currently a bug where we apply stellar transformations AFTER that
validation happens, so we don't have the ability to specify a timestamp via
stellar if it is not there already. If we had that fixed, then we could apply
the timestamp to the message in stellar, for sure.
If your project is set up for it, you can reply to this email and have your
reply appear on GitHub as well. If your project does not have this feature
enabled and wishes so, or if the feature is enabled but not working, please
contact infrastructure at infrastruct...@apache.org or file a JIRA ticket
