Re: MM2 for DR

Thanks Ryanne. However what I dont understand clearly if the case of primary crashes, what do I need to do in the secondary? For example, LB at the entrance will just point to the primary front-end so all the data will be injected in the local topic "topic1" in secondary that will be consumed for

Re: Replicas more than replication-factor

In cases like this where situation isn’t self-repairing, I stop the at-fault broker and delete the topic-partition directory/directories from the filesystem before starting the broker again. Are you using local storage on your brokers? -- Peter > On Feb 12, 2020, at 8:33 PM, Madhuri Khattar (mk

RE: Replicas more than replication-factor

In my case I figured it was broker 3 and rebooted it after deleting /admin/reassign-partitions since it was stuck there. However I am not having any luck. I still see 400+ underreplicated partitions. I replaced broker 3 as well but still there is no change after almost 7-8 hours now. Madhuri

Re: Replicas more than replication-factor

I’ve had this happen a few times when a partition reassignment was underway and one of the brokers that is a destination for the reassignment became unhealthy. This essentially stalls the reassignment indefinitely. The partition with 10 instead of 5 replicas was undergoing a reassignment where a

Replicas more than replication-factor

Hi Today there was some network glich which caused some of my topics to have replicas more than the replication-factor: $ ./kafka-topics --zookeeper sjc-ddzk-01 --topic foodee --describe Topic:foodee PartitionCount:6 ReplicationFactor:2 Configs:retention.ms=34560,segment.ms

> elaborate a bit more about the active-active Active/active in this context just means that both (or multiple) clusters are used under normal operation, not just during an outage. For this to work, you basically have isolated instances of your application stack running in each DC, with MM2 keepin

Re: [External] Re: MM2 for DR

Not sure if you saw this before, but you might be interested in some of the work Uber has done for inter-cluster replication and federation. They of course use their own tool, uReplicator (https://github.com/uber/uReplicator), instead of mirror maker, but you should be able to draw the same insight

Deleting single record from kafka topic

Is there a way to delete a single record from kafka. Not through compaction but through an actual command. I know there is the script kafka-delete-records.sh that could delete everything before the specified offset, but I want to delete a single message on the offset I specified. Is there a way

Hi, I have a question about KIP-302 and its PR & Jira ticket. I believe I understand the whole thing apart from one bit. In the Jira and the PR it says: "our use case is for multiple load balancers fronting the Kafka cluster. The Kafka advertised listeners advertise hostnames that the DNS server
