Why is Kafka fast? Kafka achieves low latency message delivery through Sequential I/O and Zero Copy Principle. The same techniques are commonly used in many other messaging/streaming platforms.Avoids Random Disk Access – as Kafka is an immutable commit log it does not need to rewind the disk and do many random I/O operations and can just access the disk in a sequential manner. This enables it to get similar speeds from a physical disk compared with memory.Apache Kafka employs sequential disk I/O for enhanced performance for implementing queues compared to message brokers in RabbitMQ. RabbitMQ queues are faster only when they’re empty, unlike Kafka that can retain lots of data with minimal overhead. Kafka is capable of processing millions of messages in a second.
Why Kafka is very fast?
Avoids Random Disk Access – as Kafka is an immutable commit log it does not need to rewind the disk and do many random I/O operations and can just access the disk in a sequential manner. This enables it to get similar speeds from a physical disk compared with memory.
Why is Kafka faster than RabbitMQ?
Apache Kafka employs sequential disk I/O for enhanced performance for implementing queues compared to message brokers in RabbitMQ. RabbitMQ queues are faster only when they’re empty, unlike Kafka that can retain lots of data with minimal overhead. Kafka is capable of processing millions of messages in a second.

Is Kafka faster than MQ?
IBM MQ vs Kafka: Communication Protocol
Kafka is quicker than most traditional message queuing systems. Because messages in Apache Kafka are not erased once the receiving system has read them, it is easier to log events.
What is faster than Kafka?
Pulsar is much faster than Kafka, thanks to its capability to deliver higher throughput with more consistent, significantly lower latency. However, the thing that really separates Pulsar from Kafka is one of its top-class features – geo-replication.
Is Kafka CPU or memory intensive?
Most Kafka deployments tend to be rather light on CPU requirements. As such, the exact processor setup matters less than the other resources. Note that if SSL is enabled, the CPU requirements can be significantly higher (the exact details depend on the CPU type and JVM implementation).
Is Apache Kafka fast?
Throughput: Kafka provides the highest throughput of all systems, writing 15x faster than RabbitMQ and 2x faster than Pulsar. Latency: Kafka provides the lowest latency at higher throughputs, while also providing strong durability and high availability.
What is better than Kafka?
Apache Pulsar incorporates the best features of Traditional Messaging systems like RabbitMQ and Pub-sub (publish-subscribe) systems like Apache Kafka. With high performance, Cloud-native package, you get the best of both worlds.

How many messages can Kafka handle per second?
Conclusion: Kafka can handle the volume
With 5 brokers it makes autoscaling the Kafka cluster to 4 vCPU and 12 GB memory we are able to sustain 200 million events per hour or 55,000 events per second simple.
Is Kafka asynchronous?
Apache Kafka: Asynchronous Messaging for Seamless Systems.
How performant is Kafka?
Throughput: Kafka provides the highest throughput of all systems, writing 15x faster than RabbitMQ and 2x faster than Pulsar. Latency: Kafka provides the lowest latency at higher throughputs, while also providing strong durability and high availability.
How Kafka is better than ActiveMQ?
Kafka is way faster than ActiveMQ. It can handle millions of messages per sec. ActiveMQ supports both message queues and publishes/subscribe messaging systems. On the other hand, Kafka is based on publish/subscribe but does have certain advantages of message-queues.
Why is Kafka over other messages?
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.

Is Kafka easier than RabbitMQ?
RabbitMQ’s queues are fastest when they’re empty, while Kafka retains large amounts of data with very little overhead – Kafka is designed for holding and distributing large volumes of messages. (If you plan to have very long queues in RabbitMQ you could have a look at lazy queues.)
What will replace Kafka?
- Google Cloud Pub/Sub.
- MuleSoft Anypoint Platform.
- IBM MQ.
- RabbitMQ.
- Amazon MQ.
- KubeMQ.
- Confluent.
- HubSpot Operations Hub.
Is RabbitMQ fast?
As you can see, IronMQ can handle a sustained enqueue rate of ~18,000 – ~19,000 messages per second and a consume rate of ~4K per second on a single queue. RabbitMQ can handle ~950 per second in and out.
How much RAM does Kafka use?
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.
How do you speed up Kafka?
Increasing the number of partitions and the number of brokers in a cluster will lead to increased parallelism of message consumption, which in turn improves the throughput of a Kafka cluster; however, the time required to replicate data across replica sets will also increase.
What is Kafka throughput?
The experiments focus on system throughput and system latency, as these are the primary performance metrics for event streaming systems in production. In particular, the throughput test measures how efficient Kafka is in utilizing the hardware, specifically the disks and the CPU.
How Kafka achieves high throughput and performance?
Maximized use of sequential disk reads and writes. Zero-copy processing of messages. Use of Linux OS page cache rather than Java heap for caching. Partitioning of topics across multiple brokers in a cluster.
