What is meant by Kafka?

Apache Kafka is a distributed publish-subscribe messaging system that receives data from disparate source systems and makes the data available to target systems in real time. Kafka is written in Scala and Java and is often associated with real-time event stream processing for big data.

Why is Kafka so fast?

Kafka relies on the filesystem for the storage and caching. The problem is disks are slower than RAM. This is because the seek-time through a disk is large compared to the time required for actually reading the data. But if you can avoid seeking, then you can achieve latencies as low as RAM in some cases.

What is Kafka in simple words?

Kafka is an open source software which provides a framework for storing, reading and analysing streaming data. Being open source means that it is essentially free to use and has a large network of users and developers who contribute towards updates, new features and offering support for new users.

How long is Kafka messages?

The Kafka cluster retains all published messages—whether or not they have been consumed—for a configurable period of time. For example if the log retention is set to two days, then for the two days after a message is published it is available for consumption, after which it will be discarded to free up space.

Why is Kafka faster 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.

What is Kafka and why it is used?

Kafka replicates topic log partitions to multiple servers. … Kafka is used to stream data into data lakes, applications, and real-time stream analytics systems.

Why does Kafka use zookeeper?

Kafka needs ZooKeeper Kafka uses Zookeeper to manage service discovery for Kafka Brokers that form the cluster. Zookeeper sends changes of the topology to Kafka, so each node in the cluster knows when a new broker joined, a Broker died, a topic was removed or a topic was added, etc.

What is the difference between Kafka and spark?
