What is RabbitMQ vs Kafka?
Summary of RabbitMQ vs Kafka
Kafka is best for big data cases that require extremely fast throughput. With its retention policies, it is also good for clients that want to connect and get a history of messages to replay. RabbitMQ would be the better option in situations where complex routing and low latency delivery is needed.
RabbitMQ is a widely used open-source message broker that helps in scaling the application by deploying a message queuing mechanism in between the two applications. It offers temporary storage for data preventing data loss. RabbitMQ Queue takes messages from the publisher and sends them to the consumer.
RabbitMQ uses a push-based model with a smart producer, which means the producer decides when to push data. A prefetch limit is defined on the consumer to stop the producer from overwhelming consumers.
RabbitMQ is based on Mnesia, a database system written in Erlang. This is used for data persistence. For example, Mnesia stores user information, the queues, and more. The nice thing about RabbitMQ is that it can run as a single instance as well as in a cluster.
RabbitMQ offers reliability, flexible routing, multiple exchange types, and easy deployment for enhanced messaging systems. RabbitMQ drawbacks: overly technical, limited queue visibility, and unclear error messages.
One of the primary differences between the two is that Kafka is pull-based, while RabbitMQ is push-based.
In RabbitMQ, a producer never sends a message directly to a queue. Instead, it uses an exchange as a routing mediator. Therefore, the exchange decides if the message goes to one queue, to multiple queues, or is simply discarded.
Kafka uses a pull-based system that allows users to request messages from particular offsets.
A program that sends messages is a producer: A queue is the name for the post box in RabbitMQ. Although messages flow through RabbitMQ and your applications, they can only be stored inside a queue. A queue is only bound by the host’s memory & disk limits, it’s essentially a large message buffer.
RabbitMQ does all the hard work of getting the message to the right place, load balancing RPC messages across multiple RPC servers, and even retasking an RPC message to another server when the server it was assigned to crashes.
RabbitMQ is a message broker software aka a queue and not a NoSql database!
Regardless of whether messages are consumed or fail to be consumed in ApsaraMQ for RabbitMQ, messages can be retained for a maximum of three days.

Is Kafka a push or pull

How does RabbitMQ send messages
A program that sends messages is a producer : A queue is the name for the post box in RabbitMQ. Although messages flow through RabbitMQ and your applications, they can only be stored inside a queue. A queue is only bound by the host's memory & disk limits, it's essentially a large message buffer.
What problem does RabbitMQ solve
RabbitMQ does all the hard work of getting the message to the right place, load balancing RPC messages across multiple RPC servers, and even retasking an RPC message to another server when the server it was assigned to crashes.
Is RabbitMQ SQL or NoSql
RabbitMQ is a message broker software aka a queue and not a NoSql database!
How long do messages stay in RabbitMQ
Regardless of whether messages are consumed or fail to be consumed in ApsaraMQ for RabbitMQ, messages can be retained for a maximum of three days.
Is Kafka a message queue or bus
In short, Kafka is a message queuing system with a couple of twists. It offers low-latency message processing just like a great message queue, along with high availability and fault tolerance, but it brings additional possibilities that simple queuing can't offer.
Is Kafka a language or tool
Apache Kafka is written in Scala and Java. Scala is a general-purpose programming language that is designed to be concise and expressive. It is often used for building distributed systems and data-intensive applications.
Is Kafka a message queue or broker

Does RabbitMQ send message to all consumers
To exit press CTRL+C # => [x] Received 'Second message..' # => [x] Received 'Fourth message….' By default, RabbitMQ will send each message to the next consumer, in sequence. On average every consumer will get the same number of messages. This way of distributing messages is called round-robin.
Why do we need RabbitMQ in microservices
The event bus implementation with RabbitMQ lets microservices subscribe to events, publish events, and receive events, as shown in Figure 6-21. RabbitMQ functions as an intermediary between message publisher and subscribers, to handle distribution.
Is RabbitMQ an ETL tool
RabbitMQ's ETL support allows RavenDB to take the role of a producer in a RabbitMQ architecture. You can create a RavenDB RabbitMQ ETL task to Extract data from the database, Transform it by your custom script, and Load the resulting JSON object to a RabbitMQ exchange as a CloudEvents message.
How many messages can RabbitMQ handle per second
RabbitMQ can also process a million messages per second but requires more resources (around 30 nodes). You can use RabbitMQ for many of the same use cases as Kafka, but you'll need to combine it with other tools like Apache Cassandra.
Is Kafka streaming or messaging
Kafka is a stream processing system used for messaging, website activity tracking, metrics collection and monitoring, logging, event sourcing, commit logs, and real-time analytics.
What is the difference between Kafka and message queue
You can think of Kafka as a message queuing system with a few tweaks. Kafka is able to provide a high availability and fault tolerance, low-latency message processing approach just like a traditional message queue. However, it brings additional possibilities that a typical message queuing system can fail to provide.
What is Kafka in simple words
In a nutshell, Kafka Streams lets you read data in real time from a topic, process that data (such as by filtering, grouping, or aggregating it) and then write the resulting data into another topic or to other systems of record.
Is Kafka an ETL tool
Kafka is a great choice for doing ETL (extract-transform-load): Connect provides the E and the L, Streams the T, and Kafka itself provides a storage buffer that provides scalability, resiliency, and replayability of the process.
What is difference between MQ and Kafka
The main difference between Kafka vs. ActiveMQ is that ActiveMQ is a message broker while Kafka is an event streaming platform.
Should I use Kafka or RabbitMQ for microservices
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.
