Kafka uses many other techniques apart from the ones mentioned above to make systems much faster and efficient: Batching of data to reduce network calls, and also converting a lot of random writes into sequential ones. Compression of batches (and not individual messages) using LZ4, SNAPPYor GZIP codecs.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.
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.
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).
How many messages can Kafka handle?
Aiven Kafka Premium-8 on UpCloud handled 535,000 messages per second, Azure 400,000, Google 330,000 and Amazon 280,000 messages / second.
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.

Why Kafka Is so Fast. Discover the deliberate design… – Medium
When someone says ‘Kafka is fast’, and assuming they are at least mildly competent, you can assume they are referring to Kafka’s ability to …
Why Apache Kafka is so Fast? – GeeksforGeeks
1. Low-Latency I/O: There are two possible places which can be used for storing and caching the data: Random Access Memory (RAM) and Disk. · 2.
Here’s what makes Apache Kafka so fast – freeCodeCamp
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 …
Now I know why Kafka is so fast!
Data falls are usually non-real-time, as is Kafka producer data persistence. Instead of writing data to disk in real time, Kafka takes advantage of modern …
Is Apache Kafka the best?
In comparison to most messaging systems Kafka has better throughput, built-in partitioning, replication, and fault-tolerance which makes it a good solution for large scale message processing applications.
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.

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.
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.
Why Kafka vs RabbitMQ?
…
RabbitMQ: Push-based approach.
| Parameter | RabbitMQ | Kafka |
|---|---|---|
| Consumer Queues | Decoupled Consumer queues | Coupled consumer partition/groups |
How much RAM does Kafka need?
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.
Does Kafka need JVM?
Kafka uses page cache memory as a buffer for active writers and readers, so after you specify JVM size (using -Xmx and -Xms Java options), leave the remaining RAM available to the operating system for page caching. Kafka needs open file descriptors for files and network connections.
What is latency in Kafka?
Apache Kafka® provides very low end-to-end latency for large volumes of data. This means the amount of time it takes for a record that is produced to Kafka to be fetched by the consumer is short. If you’re using a dedicated cluster, adding additional CKUs can reduce latency.
How is Kafka scalable?
Kafka scalability is determined largely by the number of partitions and client consumers you have (noting that partitions must be >= consumers). For Kafka sink connectors, the number of connector tasks corresponds to the number of Kafka consumers running in a single consumer group.
Can Kafka store data?
The short answer: Data can be stored in Kafka as long as you want. Kafka even provides the option to use a retention time of -1. This means “forever.”
What will replace Kafka?
- Google Cloud Pub/Sub.
- MuleSoft Anypoint Platform.
- IBM MQ.
- RabbitMQ.
- Amazon MQ.
- KubeMQ.
- Confluent.
- HubSpot Operations Hub.

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.)
Which is better Kafka or RabbitMQ?
RabbitMQ is best for transactional data, such as order formation and placement, and user requests. Kafka works best with operational data like process operations, auditing and logging statistics, and system activity.
