You have a Kafka cluster and all the topics have a replication factor of 3. One intern at your company stopped a broker, and accidentally deleted all the data of that broker on the disk. What will happen if the broker is restarted?

AThe broker will start, and other topics will also be deleted as the broker data on the disk got deleted

BThe broker will start, and won't be online until all the data it needs to have is replicated from other leaders

Oh boy, I can just picture the intern panicking and frantically hitting the restart button. 'Please don't crash, please don't crash!' Gotta keep that Kafka cluster healthy, folks!

Hmm, I'm going with B. As long as the replication factor is 3, the other brokers should have the data covered. Though I bet the intern's getting an earful for that little incident.

C, the broker will crash. I mean, come on, deleting all the data? That's a surefire way to make a broker go down in flames. Literally.

D! The broker will start without any data, and if it becomes a leader, we'll have data loss. Ouch, that's a tough situation. Gotta be extra careful with those brokers.

Oh no, that sounds risky. Hopefully, the replication process happens smoothly and we don't lose any important data.

I think the correct answer is B. The broker will start, but it won't be online until all the data it needs is replicated from the other leaders. Losing a broker is never good, but at least the data is safe.

I agree. It's a good practice to have replication factor in Kafka clusters to prevent data loss in case of failures.

Yes, that's correct. It's important to have replication factor to ensure data availability and fault tolerance.

I'm not sure, but I think the answer might be D. If the broker becomes leader without any data, there could be data loss.

I agree with Arletta. If the data needs to be replicated, it makes sense that the broker won't be online right away.
