I'm new in Kafka and while reading about synchronous replication in Kafka here I was surprised by the following paragraph:
"For simplicity, reads are always served from the leader. Only messages up to the HW are exposed to the reader"
Does anybody know if this means that it is not possible to read from replicas of a partition in Kafka? The link is from February 2013, maybe things have changed since. Any explanation about about reads with synchronous replication will be appreciated.
