The Kafka Replication Tool is used to create a high-level design for the replica maintenance process. The following are some of the replication tools available:

Preferred Replica Leader Election Tool: Partitions are spread to many brokers in a cluster, each copy known as a replica, using the Preferred Replica Leader Election Tool. The leader is frequently referred to as the favored replica. The brokers normally spread the leader position equitably across the cluster for various partitions, but owing to failures, planned shutdowns, and other factors, an imbalance can develop over time. This tool can be used to preserve the balance in these situations by reassigning the preferred replicas, and hence the leaders.

Topics tool: The Kafka topics tool is in charge of all administration operations relating to topics, including:

Listing and describing the topics.

Topic generation.

Modifying Topics.

Adding a topic's dividers.

Disposing of topics.

Tool to reassign partitions: The replicas assigned to a partition can be changed with this tool. This refers to adding or removing followers from a partition.

StateChangeLogMerger tool: The StateChangeLogMerger tool collects data from brokers in a cluster, formats it into a central log, and aids in the troubleshooting of state change issues. Sometimes there are issues with the election of a leader for a particular partition. This tool can be used to figure out what's causing the issue.

Change topic configuration tool: used to create new configuration choices, modify current configuration options, and delete configuration option
