Hi again community, I have a question which I cannot find the answer to in the docs. Because of our ACL policies in Kafka, we would like to know if read access is enough for Data Hub on the MCE topic, or if it needs write to it too? Is it enough if it can read from MCE and write to MAE?

Actually, it's the other way around... You will need READ access to MetadataAuditEvent Topic (MAE) and WRITE access to MetadataChangeEvent (MCE), which is really representative of a Proposal stream

Hi @rapid-sundown-8805 if the question is about Datahub-serving layer, then yes READ on MCE and READ+WRITE on MAE would be enough. Ingestion layer will need to WRITE to MCE if you use Kafka transport.

Thanks guys! That's clear 🙂 And seems I switched MCE and MAE around somehow in my question.

Cool!

Hey again, I just realized you guys told me the opposite thing, but I guess from the datahub-serving layers perspective, it reads MCE and writes to MAE, right? And ingestion writes to MCE. Is that correct? Just to be sure 😛

😀 Yes. Datahub serving reads MCE and writes to MAE. Ingestion writes to MCE (if configured to use Kafka transport) otherwise goes straight to gms which writes to MAE.

Thank you guys and thanks for an amazing product and an awesome contribution to the open source community! 👍
