Why Is Kafka Over Other Messages?

Why Kafka is better than other messaging systems?

Kafka is Highly Reliable.

Kafka replicates data and is able to support multiple subscribers.

Additionally, it automatically balances consumers in the event of failure.

That means that it’s more reliable than similar messaging services available..

Can Kafka replace MQ?

While IBM MQ or JMS in general is used for traditional messaging, Apache Kafka is used as streaming platform (messaging + distributed storage + processing of data). Both are built for different use cases. You can use Kafka for “traditional messaging”, but not use MQ for Kafka-specific scenarios.

What is Kafka not good for?

Kafka is not designed to be a task queue. There are other tools that are better for such use cases, for example, RabbitMQ. If you need a database, use a database, not Kafka. Kafka is not good for long-term storage.

Franz Kafka’s work is characterized by anxiety and alienation, and his characters often face absurd situations. He is famous for his novels The Trial, in which a man is charged with a crime that is never named, and The Metamorphosis, in which the protagonist wakes to find himself transformed into an insect.

What is the difference between JMS and MQ?

The difference being that JMS messages have some standard header fields at the begining of the message buffer and “native” mq messages contain just the data your program sent to the buffer. Performance is not the only reason to send plain messages (MQ format) without the JMS Headers from JMS Client to MQ Server.

What is the difference between JMS and Kafka?

JMS: Difference Explained. Apache Kafka is a pub-sub tool that is commonly used for message processing, scaling, and handling a huge amount of data efficiently. Whereas Java Message Service aka JMS is a message service that is designed for more complicated systems such as Enterprise Integration Patterns.

Is Kafka pull or push?

With Kafka consumers pull data from brokers. Other systems brokers push data or stream data to consumers. … Since Kafka is pull-based, it implements aggressive batching of data. Kafka like many pull based systems implements a long poll (SQS, Kafka both do).

Why use Kafka over RabbitMQ?

Kafka offers much higher performance than message brokers like RabbitMQ. It uses sequential disk I/O to boost performance, making it a suitable option for implementing queues. It can achieve high throughput (millions of messages per second) with limited resources, a necessity for big data use cases.

How do I stop duplicate text in Kafka?

How do I get exactly-once messaging from Kafka?Use a single-writer per partition and every time you get a network error check the last message in that partition to see if your last write succeeded.Include a primary key (UUID or something) in the message and deduplicate on the consumer.

Can Kafka lost messages?

Kafka is speedy and fault-tolerant distributed streaming platform. However, there are some situations when messages can disappear. It can happen due to misconfiguration or misunderstanding Kafka’s internals.

Is Kafka exactly once?

Initially, Kafka only supported at-most-once and at-least-once message delivery. However, the introduction of Transactions between Kafka brokers and client applications ensures exactly-once delivery in Kafka.

Is Kafka at least once?

Introduction To Message Delivery Semantics In Kafka They are: At most once, at least once, exactly once. In at most once delivery, the message is either delivered or not delivered. This delivery semantic is suited for use cases where losing some messages do not affect the result of processing the complete data.
