Kafka - is there a quorum a used for reading when min isrs greater than 1

I am just wondering if I have no of replicas as 3, and
if min.insync.replicas > 1, in that case does a read require from read
quorum or just the leader always serves the read request?

Thanks & Regards,

Hi,

The leader always serves all requests. Replicas are used just for high
availability (i.e to become leader if needed).
