Dear developers,
In the paper "Kafka: A Distributed Messaging System for Log Processing, Jay
Kreps, Neha Narkhede, Jun Rao from LinkedIn, at NetDB workshop 2011",
you mentioned this:
"If a broker goes down, any message stored on it not yet consumed becomes
unavailable. If the storage system on a broker is permanently damaged, any
unconsumed message is lost forever. In the future, we plan to add built-in
replication in Kafka to redundantly store each me ssage on multiple brokers."
I'm curious, does the built-in replication has been implemented or it's still
in progress? Currently, is there anyway to recover the died broker and
unconsumed messages?
Thanks,
Haoming
