A lot of businesses are adopting Apache Kafka as they are aware of the great benefits it brings to the business. In this post, we will go one step ahead, explaining what Kafka tools are. For first-time readers, Kafka is a publish-subscribe messaging system that enables users to send messages between applications, processes, and servers. It is a software where topics are defined and processed. Further, applications can be linked to this system and transmit a message to the topic. The message may entail any type of information, from a personal blog to a public event or it can be a plain text message promoting or triggering any other event. The focus of this post is Kafka tools that are categorized into two types: system tools and replication tools.

A Kafka Tool

A Kafka Tool is a GUI application to use and manage Apache Kafka clusters. It offers an intuitive UI that enables the users to quickly view objects in a Kafka cluster and the messages saved in the topics of the cluster. It has features designed for both developers and administrators.

  • Kafka System Tools

By using the run class script, Kafka system tools can be run from a command line. Its syntax is:

bin/kafka-run-class.sh package.class  – options

There are various kinds of Kafka system tools:

  • Kafka Migration Tool

To shift the Kafka broker from one version to another, Kafka Migration Tool is used. 

  • Mirror Maker

Kafka’s mirroring feature makes itNog  possible to maintain a replica of an existing Kafka cluster. Mirror Maker tool is used to enable mirroring. 

  • Consumer Offset Checker

Kafka Topic, logSize, Off-set, Consumer Group, Owner for the specified set of Topics, Partitions, and Consumer Group are exhibited by Consumer Off-set Checker Tool.

  • Kafka Replication Tool

Kafka replication tool is a high-level design tool. Basically, to ensure prolonged durability and higher availability, Kafka replication tool helps. However, Kafka Replication tools include−

  • Create Topic Tool

For making a topic by replication factor and as default number of partitions Create Topic Tool is used. Also, it uses Kafka’s default scheme for doing replica assignment.

  • List Topic Tool

It shows the information for a topics’ list. However, if there are no topics on the command line, the tool queries Zookeeper to acquire all the topics and lists the information for them. Furthermore, the tool displays numerous fields, like topic name, leader, partition, replicas, isr.

  • Add Partition Tool

Essentially, the number of partitions for a topic must be quantified, at the time of formation of the topic. But, it is likely that when the capacity of the topic will rise, we may require more partitions for the topic. Therefore, to add more partition in a specific topic, Add Partition Tool is used. Also, it enables the manual replica assignment of the added partitions.

Concluding thoughts

Apache Kafka has become one of the most useful platforms for businesses across various industries due to its intuitive features. An increasing number of businesses are adopting Kafka for diverse requirements pertaining to operations. In this article, we briefly explained what Kafka is and also discussed the key Kafka tools and their different types.
