--------------------------------------
Summary: Document the behavior of NewPartitions#increaseTo when
the replicas is not consistent
Key: KAFKA-21252
URL: https://issues.apache.org/jira/browse/KAFKA-21252
Project: Kafka
Issue Type: Improvement
Reporter: Chia-Ping Tsai
Assignee: Chia-Ping Tsai
/**
* Increase the partition count for a topic to the given \{@code
totalCount}.
* The assignment of new replicas to brokers will be decided by the broker.
*
* @param totalCount The total number of partitions after the operation
succeeds.
*/
public static NewPartitions increaseTo(int totalCount) {
return new NewPartitions(totalCount, null);
}
We don't define the behavior if the replicas of different partitions is not
identical. What the number of replicas will be created by this method? I guess
it depends on the first partition, but I haven't checked that from source code
