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.

What is Kafka audit?

Audit logs provide a way to capture, protect, and preserve authorization activity into topics in Kafka clusters on Confluent Platform using Confluent Server Authorizer. The primary value of audit logs is that they provide data you can use to assess security risks in your local and remote Kafka clusters.

Is Kafka good for queue?

RabbitMQ’s queues are fastest when they’re empty, while Kafka is designed for holding and distributing large volumes of messages. Kafka retains large amounts of data with very little overhead. People that are trying out RabbitMQ are probably not aware of the the feature lazy queues.

Why I should use Kafka?

Kafka can handle a lot of data per unit of time. It also has low latency, which allows for the processing of data in a real-time mode. Apache Kafka is written in Scala and Java, but it is compatible with many other popular programming languages. Kafka is different from traditional message queues (like RabbitMQ).

How is Kafka different from MQ?

While ActiveMQ (like 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.

How do I view Kafka logs?

If you open script kafka-server-start or /usr/bin/zookeeper-server-start , you will see at the bottom that it calls kafka-run-class script. And you will see there that it uses LOG_DIR as the folder for the logs of the service (not to be confused with kafka topics data).

What is audit logging in Microservices?

An audit log is the simplest, yet also one of the most effective forms of tracking temporal information. The idea is that any time something significant happens you write some record indicating what happened and when it happened. An audit log can take many physical forms. The most common form is a file.

Why Kafka is fast?

Compression & Batching of Data: Kafka batches the data into chunks which helps in reducing the network calls and converting most of the random writes to sequential ones. It’s more efficient to compress a batch of data as compared to compressing individual messages.

What is user audit log?

Can Kafka handle real time data pipeline?

Kafka can handle real-time data pipeline. Since we need to find a technology piece to handle real-time messages from applications, it is one of the core reasons for Kafka as our choice.

What are the advantages of Kafka over other platforms?

It is capable of handling these messages with the very low latency of the range of milliseconds, demanded by most of the new use cases. c. Fault-Tolerant. One of the best advantages is Fault Tolerance. There is an inherent capability in Kafka, to be resistant to node/machine failure within a cluster.
