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.

Does Netflix use Kafka?

Apache Kafka is an open-source streaming platform that enables the development of applications that ingest a high volume of real-time data. It was originally built by the geniuses at LinkedIn and is now used at Netflix, Pinterest and Airbnb to name a few.

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.

Is Kafka at least once?

At-least-once semantics: if the producer receives an acknowledgement (ack) from the Kafka broker and acks=all, it means that the message has been written exactly once to the Kafka topic.

Is Kafka easy to learn?

IS IT EASY? Unfortunately, it's not. For those who are new to Kafka, it can be difficult to grasp the concept of Kafka brokers, clusters, partitions, topics, and logs. You'll also need to pick up how producers and consumers store and retrieve messages on Kafka clusters.

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.

Does Kafka use RAM?

RAM: In most cases, Kafka can run optimally with 6 GB of RAM for heap space. For especially heavy production loads, use machines with 32 GB or more. Extra RAM will be used to bolster OS page cache and improve client throughput.

Is Pulsar better than Kafka?

Kafka provides the lowest latency (5ms at p99) at higher throughputs, while also providing strong durability and high availability*. Kafka in its default configuration is faster than Pulsar in all latency benchmarks, and it is faster up to p99.

Is Kafka a hype?

Apache Kafka is definitely more than just hype. As with any new technology, you have to manage expectations every now and then. But more and more companies are realizing that they can offer digital services that are innovative and disruptive if the right data is provided and integrated.

What problems does Kafka solve?

The problem they originally set out to solve was low-latency ingestion of large amounts of event data from the LinkedIn website and infrastructure into a lambda architecture that harnessed Hadoop and real-time event processing systems. The key was the "real-time" processing.

Is Kinesis same as Kafka?

Kafka handles data streams in real-time (like Kinesis.) It's used to read, store, and analyze streaming data and provides organizations with valuable data insights. Uber, for example, uses Kafka for business metrics related to ridesharing trips. The big difference between Kinesis and Kafka lies in the architecture.

Why is it called Kafka?
