Good evening Apache Kafka users group, I am architecting an Apache Kafka 5 node stretch cluster for 2 datacenters. If we set min.isr to 4 and acks to 4, it would seem that we have a full record of consumer and producer events on at least one node should datacenter 1 get hit by a meteor.
Reviewing output of: ./bin/kafka-consumer-groups.sh --bootstrap-server localhost:9092 --describe On each node, one node should have a LAG value of 1 and the other should have a value of 0 for each parititon -- can I rely on that to compile an authoritative broker to elect? Is the data I'm looking for easier to retrieve if I use a zookeeper ensemble to record the offsets and perform elections? Or should I simply set acks=all? Thanks in advance for any assistance anyone can provide, Joseph Hammerman
