Class PartitionReplicaIngestionContext

java.lang.Object

com.linkedin.davinci.kafka.consumer.PartitionReplicaIngestionContext

public class PartitionReplicaIngestionContext
extends java.lang.Object

This class is for wrapping the information about the role of the partition replica on that host to AggKafkaConsumerService to achieve finer granularity of consumer assignment. Those information should be triggered by store version role (future, current and backup), workload type and leader or follower state. Version role and workload type information are properly managed by StoreIngestionTask to be sent to AggKafkaConsumerService. We could add more information regarding this partition replica if needed in the future.
