For GDPR a lot of us has to do exportable 'user activity'. Can you in theory have a topic/user ( we had like 50 million users) and publish any user activity to that topic?
Most commonly what I hear people doing for this is either one of two approaches (or a combination of both):
- encrypt the user data and delete the key, eventually the user data will get removed
- regularly compact the topic (pulsar has a compaction feature) and write in a tombstone record which will remove any user data after compaction
