Hi All
Just double checking
If i have created a topic with replication factor 1
does it mean i dont have replication
if one of my disks crashes do i loose data?
Thanks
Avi
Hi,
I have a cluster of 3 Kafka brokers, and replication factor is 2. This
means I can tolerate failure of 1 node without data loss.
Recently, one of my node crashed and some of my partitions went offline.
I am not sure if this should be the case. Am I missing something.

Hi All,
I have two nodes kafka cluster and using replication factor 2. If both the node
is running, then i am able to push data, but if any nodes goes down, then
getting exception. I explored and found that, the default replication factor
mode is quorum, means at least (f+1) node must be availa
Hello Avi,
Yes, replication factor of 1 means just one lead replica gets assigned for
the topic partitions.
To achieve HA of messages there are more things to watch out, not only
replication factor - metadata/ZK HA, producer acks, min-in-sync replicas,
rack awareness for replica assignment to nam
whats your config for min.insync.replicas?

if RF=2 and min.insync.replicas=1 (the default) then you shouldn't have
offline partitions if 1 of 3 brokers is down.
I'd first double check your topic config (and broker defaults) for the one
that went offline to verify RF/Min. Be sure to check each partition they
can be different! ( kafka-topics
Kafka tolerates 2f failures with 2f+1 replicas by default. What error are
you seeing?
Thanks,
