What is use of Kafka?
Kafka is primarily used to
build real-time streaming data pipelines and applications that adapt to the data streams
. It combines messaging, storage, and stream processing to allow storage and analysis of both historical and real-time data.
What is Kafka and how it works?
Apache Kafka is
a publish-subscribe based durable messaging system
. A messaging system sends messages between processes, applications, and servers. … Another application may connect to the system and process or re-process records from a topic. The data sent is stored until a specified retention period has passed by.

Why Kafka is so 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 difference between Kafka and MQ?
Apache Kafka is designed to enable the streaming of real time data feeds and is an open source tool that users can access for free. IBM MQ is a traditional message queue system that allows multiple subscribers to pull messages from the end of the queue.

What are the key features of Kafka?

- b. High-Volume. …
- c. Data Transformations. …
- d. Fault Tolerance. …
- e. Reliability. …
- f. Durability. …
- g. Performance. …
- h. Zero Downtime.
Why Kafka is better than 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.
Is Kafka a database?

a database
. It provides ACID guarantees and is used in hundreds of companies for mission-critical deployments.
