I think we'd better add a new page/section for pulsar system topics, system topics are just a topic name internally in Pulsar, __change_events is one of them.
- What is the system topic in Pulsar
- Why are we using system topic
- How many system topics that Pulsar have
- How to enable system topic
- System topic limitations
@codelipenghui Makes sense. Who can provide the draft? |

This should have been __transaction_log_.

I will update it to __transaction_log_${tc_id} in a follow-up PR. Thank you both.
