Quick Answer: When Should We Use Kafka?

Is Kafka overkill?

With Kafka, each partition can be consumed by single consumer only.

If you are only processing few thousand messages each day then Kafka is probably an overkill.

Kafka is really built for handling large scale stream processing so setting up & maintaining it is not worth it if you don’t have/anticipate scale..

Is Kafka worth learning?

Strong open-source community is a guarantee that certain technology is going to be there for some time, and therefore is worth learning and investing the time into. Kafka has gained huge popularity and success in companies like LinkedIn, Netflix, Spotify, Klarna etc.

Does Kinesis use Kafka?

Where do we use Kafka?

Kafka is often used for operational monitoring data. This involves aggregating statistics from distributed applications to produce centralized feeds of operational 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.

Is Kafka real time?

Apache Kafka is a distributed streaming platform. At its core, it allows systems that generate data (called Producers) to persist their data in real-time in an Apache Kafka Topic. … Behind the scenes, Kafka is distributed, scales well, replicates data across brokers (servers), can survive broker downtime, and much more.

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. Apache Kafka is a software where topics can be defined (think of a topic as a category), applications can add, process and reprocess records.

Does Netflix use Kafka?

Netflix embraces Apache Kafka® as the de-facto standard for its eventing, messaging, and stream processing needs. Kafka acts as a bridge for all point-to-point and Netflix Studio wide communications.

Can Kafka replace database?

Kafka as Query Engine and its Limitations Therefore, Kafka will not replace other databases. It is complementary. The main idea behind Kafka is to continuously process streaming data; with additional options to query stored data. Kafka is good enough as database for some use cases.

What is difference between Kafka and spark?

Key Difference Between Kafka and Spark Kafka is a Message broker. Spark is the open-source platform. … Kafka provides real-time streaming, window process. Where Spark allows for both real-time stream and batch process.

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.

What is the advantage of Kafka?

Kafka persists the messages on the disks, which provides intra-cluster replication. This makes for a highly durable messaging system. Kafka is Highly Reliable. Kafka replicates data and is able to support multiple subscribers.

Kafka is easy to set up and use, and it is easy to figure out how Kafka works. However, the main reason Kafka is very popular is its excellent performance. … In addition, Kafka works well with systems that have data streams to process and enables those systems to aggregate, transform, and load into other stores.

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.

Is Kafka memory?

Kafka avoids Random Access Memory, it achieves low latency message delivery through Sequential I/O and Zero Copy Principle. Sequential I/O: Kafka relies heavily on the filesystem for storing and caching messages. There is a general perception that “disks are slow”, which means high seek time.

What is difference between Kafka and JMS?

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.
