Kafka Offset Types

Kafka is designed to be flexible on how the offsets are managed. Consumer can choose arbitrary storage and format to persist kafka offsets. Kafka Eagle currently support following popular storage format:

  • Zookeeper. Old version of Kafka (0.8.2 before) default storage in Zookeeper.
  • Kafka. New version of Kafka (0.10.0 in the future) default recommend storage in Kafka Topic(__consumer_offsets).

Kafka Eagle supports multiple offset storage paths. If you store them in Zookeeper and Kafka, you can configure them like this.

# Set kafka cluster alias
kafka.eagle.zk.cluster.alias=cluster1,cluster2

# Set kafka cluster zookeeper address
cluster1.zk.list=xdn1:2181,xdn2:2181,xdn3:2181
cluster2.zk.list=tdn1:2181,tdn2:2181,tdn3:2181

# Set kafka cluster offset storage path
cluster1.kafka.eagle.offset.storage=kafka
cluster2.kafka.eagle.offset.storage=zookeeper
