what is Best Practices of kafka mirror maker 2

[5z3nnr8v-git]

Now, i config mm2,properties this below

clusters=DC1,DC2 DC1.bootstrap.servers = broker1-dev1:30011, broker2-dev1:30012, broker3-dev1:30013 DC2.bootstrap.servers = broker1-dev2:30011, broker2-dev2:30012, broker3-dev2:30013

DC1.config.storage.replication.factor = 3 DC2.config.storage.replication.factor = 3

DC1.offset.storage.replication.factor = 3 DC2.offset.storage.replication.factor = 3

DC1.status.storage.replication.factor = 3 DC2.status.storage.replication.factor = 3

DC1->DC2.enabled = true DC2->DC1.enabled = true

offset-syncs.topic.replication.factor = 3 heartbeats.topic.replication.factor = 3 checkpoints.topic.replication.factor = 3

topics = .* groups = .*

task.max = 2 replication.factor = 3 refresh.topics.enabled = true sync.topics.configs.enabled = true refresh.topics.interval.seconds = 10

topic.blacklist = .[-.]internal, ..replica, __consumer_offsets groups.blacklist = console-consumer-., connect-., __.*

DC1->DC2.emit.heartbeats.enabled = true DC1->DC2.emit.checkpoints.enabled = true

DC2->DC1.emit.heartbeats.enabled = true DC2->DC1.emit.checkpoints.enabled = true What is the expected behavior? I have a test case this below.

Create topic on DC1 name topicTest1, It will replica sync to DC2 and on the DC2 will have topic in name DC1.testTopic1. next step, I produce message to topicTest1 on DC1 and message will sync to DC1.testTopic1 on DC2. last step I produce message to DC1.testTopic1 on DC2 but message not able sync to topicTest1 on DC1. I have a question. in test last step at bullet 3. the message is produced to DC1.testTopic1 on DC2 should already sync to topicTest1 on DC1, or not sync ?

If not sync, please explain me
