Constructor Details

RequestMetadata

public RequestMetadata(String topic,
 Integer numPartitions,
 Short replicationFactor,
 Map<Integer,List<Integer>> replicasAssignments,
 Map<String,String> configs)

Create an instance of this class with the provided parameters. This constructor is public to make testing of CreateTopicPolicy implementations easier.

Parameters:

topic - the name of the topic to created.

numPartitions - the number of partitions to create or null if replicasAssignments is set.

replicationFactor - the replication factor for the topic or null if replicaAssignments is set.

replicasAssignments - replica assignments or null if numPartitions and replicationFactor is set. The assignment is a map from partition id to replica (broker) ids.

configs - topic configs for the topic to be created, not including broker defaults. Broker configs are passed via the configure() method of the policy implementation.
