We are using version 2.3.1. Two more pieces are information wrt Luke's answer. Assume that retention of the data is Y and you turn on the node 3 after time Y so the data on node 3 is old and would be deleted regardless, so there is no point in doing another partition reassignment because the dat

It should delete the old data log based on retention of topic. What kafka version you are using ? On 9/15/20, 7:48 PM, "Dima Brodsky" wrote: [External] Hi, I have a question, when you start kafka on a node, if there is a random replica log should it delete it on startup? Her

Hi Dima, They'll stick around. I think the point is that when node 3 is back, you should do partition reassignment so that the pre-existed partition/replica data can be reused. But for your question, the unused log won't delete is a bug or as designed... I think it is working as designed and it sh

Hi Shaohan, Thanks for your inputs. I did look at request total time and request queue time metrics and it looks to be normal. The broker was restarted a couple times and I saw some spikes during that time alone. The kafka broker logs don't have any errors at all. The issue started around 11:30 an

Hi, I have a question, when you start kafka on a node, if there is a random replica log should it delete it on startup? Here is an example: Assume you have a 4 node cluster. Topic X has 3 replicas and it is replicated on nodes 1, 2, and 3. Now you shutdown node 3 and you place the replica tha

You could check if there are any performance issues on the broker. Broker metrics such as kafka_network_requestmetrics_totaltimems and kafka_network_requestmetrics_requestqueuetimems might do you a favor. And your acks config would also affect the e2e latency On Wed, 16 Sep 2020 at 05:08, Navnee

Hello Samuel, I tried other consumer config and it worked. Basically, it should follow the pattern `source-cluster-alias.consumer.`. In your case, I think it should be `source-cluster-alias.consumer.auto.offset.reset`. But feel free to try other consumer config and see if they work On 2020/09/
