Summary: Remove Redundant Validation in StripedReplicaPlacer
Key: KAFKA-19612
URL: https://issues.apache.org/jira/browse/KAFKA-19612
Project: Kafka
Issue Type: Improvement
Reporter: Jialun Peng
Assignee: Jialun Peng
Currently, the following validation checks are performed twice for each
partition placement:
# {{throwInvalidReplicationFactorIfNonPositive()}}
# {{throwInvalidReplicationFactorIfTooFewBrokers()}}
# {{throwInvalidReplicationFactorIfZero()}}
These checks are already performed in the public {{place()}} method before the
partition placement loop begins. Since the cluster state and replication factor
don't change during the placement operation, these checks only need to be
performed once.
This redundant validation could be removed from the inner loop to improve
performance, especially when placing many partitions.
