Let’s have a look at what Kafka is before we get into the heart of this piece.
Kafka is capable of processing a large volume of data in a short amount of time. It also has a low latency, which enables it to process data in real-time. Despite being designed in Scala and Java, Apache Kafka may be used with a variety of programming languages.
RabbitMQ and other traditional message queues are not equal to Kafka. RabbitMQ deletes messages as soon as the consumer confirms them, whereas Kafka keeps them for a predetermined period of time (the default is 7 days) after they are received. RabbitMQ may also send messages to consumers and monitor their load. It sets the maximum number of messages that each consumer should be able to process at any given time. Kafka messages, on the other hand, can be retrieved by consumers.
It’s designed to scale horizontally as more nodes are added.
It can be used for fault-tolerant storage, publishing, and subscribing to a record stream. The programs are made to handle data on consumption and timing. Log partitions are replicated across many hosts using Kafka. Code modifications are submitted by developers and users, and the system saves, reads, and analyzes them in real-time. For messaging, online activity tracking, log aggregation, and commit logs, Kafka is employed. Although Kafka can be used as a database, it is missing a data schema and indexes.

Q1: What are the features of Kafka?
As we all know, Kafka includes a slew of features that have revolutionized the Big Data industry, including:
- Kafka is a high-throughput, fault-tolerant messaging system.
- In Kafka, a Topic is a built-in patriation scheme.
- Kafka also has a replication mechanism built-in.
- Kafka is a distributed messaging system capable of handling large amounts of data and transferring messages from one sender to another.
- Kafka can also save the messages to storage and replicate them across the cluster.
- For synchronization and collaboration with other services, Kafka uses Zookeeper.
- Apache Spark gets a lot of help from Kafka.
Q2: What is meant by Kafka schema registry?
In a Kafka cluster, Avro schemas are kept in a Schema Registry, which is accessible to both producers and consumers. Producers and consumers can set compatibility criteria for easy serialization and de-serialization using Avro schemas. The Kafka Schema Registry is used to ensure that the consumer and producer schemas are identical. Producers just need to submit the schema ID, not the whole schema, when utilizing the Confluent schema registry in Kafka. The customer searches the Schema Registry for the suitable schema using the schema ID.
