Hi guys,
I have a confusion about whether it will lost data when I rolling restart
Kafka cluster.
Suppose that Kafka cluster has 4 brokers: A, B, C, D, and 4 partitions of a
topic which name is “test-topic” are allocated on these brokers with
balance: p1 for A, p2 for B, p3 for C, p4 for D;
1 I stop all these brokers.
2 I just restart broker A, and waiting for a few minutes (such as 5 minutes);
The question is: broker A found that only partition 1 of “test-topic” is
existed(because other brokers are still broken down), will A abandon the data
of partition2, 3,4, and recreate these partition?
