By saying cluster info, I am referring to information like
- subscribed consumers/consumer groups
- read and committed offsets
- leaders and followers of a partition
- topics on the server etc.
Does zookeeper keep this info in its own db (though I never heard of zookeeper having any db of its own till date) or it stores this info in the Kafka cluster on some topics etc?
EDIT: and a follow up Q: How does Zookeeper retrive the consumer offsets from __consumer_offsets topic?
