Rabbitmq vs kafka vs redis vs activemq

As ofSlack was handling a peak of 1. Until recently, Slack had continued to depend on their initial job queue implementation system based on Redis. While it had allowed them to grow exponentially and diversify their services, they soon outgrew the existing system. Also, dequeuing jobs required memory that was unavailable.

Allowing job workers to scale up further burdened Redis, slowing the entire system. Slack decided to use Kafka to ease the process and allow them to scale up without getting rid of the existing architecture. To build on it, they added Kafka in front of Redis leaving the existing queuing interface in place.

A stateless service called Kafkagate was developed in Go to enqueue jobs to Kafka. Kafkagate's design reduces latency while writing jobs and allows greater flexibility in job queue design. JQRelay, a stateless service, is used to relay jobs from a Kafka topic to Redis. It ensures only one relay process is assigned to each topic, failures are self-healing, and job-specific errors are corrected by re-enqueuing the job to Kafka.

The new system was rolled out by double writing all jobs to both Redis and Kafka, with JQRelay operating in 'shadow mode' - dropping all jobs after reading it from Kafka. Jobs were verified by being tracked at each part of the system through its lifetime. By using durable storage and JQRelay, the enqueuing rate could be paused or adjusted to give Redis the necessary breathing room and make Slack a much more resilient service.

Managing this variety requires a reliably high-throughput message-passing technology. We use Celery 's RabbitMQ implementation, and we stumbled upon a great feature called Federation that allows us to partition our task queue across any number of RabbitMQ servers and gives us the confidence that, if any single server gets backlogged, others will pitch in and distribute some of the backlogged tasks to their consumers. Lumosity is home to the world's largest cognitive training database, a responsibility we take seriously.

For most of the company's history, our analysis of user behavior and training data has been powered by an event stream--first a simple Node. Both supported decent throughput and latency, but they lacked some major features supported by existing open-source alternatives: replaying existing messages also lacking in most message queue-based solutionsscaling out many different readers for the same stream, the ability to leverage existing solutions for reading and writing, and possibly most importantly: the ability to hire someone externally who already had expertise.

We ultimately migrated to Kafka in early- to mid, citing both industry trends in companies we'd talked to with similar durability and throughput needs, the extremely strong documentation and community.

Understanding the internals and proper levers takes some commitment, but it's taken very little maintenance once configured. Heron looks great, but we already had a programming model across services that was more akin to consuming a message consumers than required a topology of bolts, etc.

Heron also had just come out while we were starting to migrate things, and the community momentum and direction of Kafka felt more substantial than the older Storm. If we were to start the process over again today, we might check out Pulsaralthough the ecosystem is much younger.

We've been using RabbitMQ as Zulip's queuing system since we needed a queuing system. What I like about it is that it scales really well and has good libraries for a wide range of platforms, including our own Python. So aside from getting it running, we've had to put basically 0 effort into making it scale for our needs.

As an open source project, we've handled this issue by really carefully scripting the installation to be a failure-proof configuration in this case, setting the RabbitMQ hostname to But it was a real pain to get there and the process of determining we needed to do that caused a significant amount of pain to folks installing Zulip.

But overall, I like that it has clean, clear semanstics and high scalability, and haven't been tempted to do the work to migrate to something like Redis which has its own downsides.Managing this variety requires a reliably high-throughput message-passing technology.

I use Kafka because it has almost infinite scaleability in terms of processing events could be scaled to process hundreds of thousands of eventsgreat monitoring all sorts of metrics are exposed via JMX.

Downsides of using Kafka are: - you have to deal with Zookeeper - you have to implement advanced routing yourself compared to RabbitMQ it has no advanced routing. The question for which Message Queue to use mentioned "availability, distributed, scalability, and monitoring".

I don't think that this excludes many options already. I does not sound like you would take advantage of Kafka 's strengths replayability, based on an even sourcing architecture. You could pick one of the AMQP options. It ticks the boxes you mentioned and on top you will get a very flexible system, that allows you to build the architecture, pick the options and trade-offs that suite your case best. For more information about RabbitMQ, please have a look at the linked markdown I assembled.

The second half explains many configuration options. It also contains links to managed hosting and to libraries though it is missing Python's - which should be Puka, I assume. I used Kafka originally because it was mandated as part of the top-level IT requirements at a Fortune client. What I found was that it was orders of magnitude more complex So for any case where utmost flexibility and resilience are part of the deal, I would use Kafka again.

But due to the complexities involved, for any time where this level of scalability is not required, I would probably just use Beanstalkd for its simplicity.

I tend to find RabbitMQ to be in an uncomfortable middle place between these two extremities. Automations are what makes a CRM powerful. With Celery and RabbitMQ we've been able to make powerful automations that truly works for our clients. Such as for example, automatic daily reports, reminders for their activities, important notifications regarding their client activities and actions on the website and more.

We use Celery basically for everything that needs to be scheduled for the future, and using RabbitMQ as our Queue-broker is amazing since it fully integrates with Django and Celery storing on our database results of the tasks done so we can see if anything fails immediately.

If you can think in queues then RabbitMQ should be a viable solution for integrating disparate systems. Front-end messages are logged to Kafka by our API and application servers. We have batch processing on the middle-left and real-time processing on the middle-right pipelines to process the experiment data.

For batch processing, after daily raw log get to s3, we start our nightly experiment workflow to figure out experiment users groups and experiment metrics. We use our in-house workflow management system Pinball to manage the dependencies of all these MapReduce jobs. The poster child for scalable messaging systems, RabbitMQ has been used in countless large scale systems as the messaging backbone of any large cluster, and has proven itself time and again in many production settings.

Rabbit acts as our coordinator for all actions that happen during game time. All worker containers connect to rabbit in order to receive game events and emit their own events when applicable. Used as central Message Broker; off-loading tasks to be executed asynchronous, used as communication tool between different microservices, used as tool to handle peaks in incoming data, etc.Thanks to the writer of this article.

Because our storage layer s3 is decoupled from our processing layer, we are able to scale our compute environment very elastically. We have several semi-permanent, autoscaling Yarn clusters running to serve our data processing needs. While the bulk of our compute infrastructure is dedicated to algorithmic processing, we also implemented Presto for adhoc queries and dashboards. At Stitch Fix, algorithmic integrations are pervasive across the business. We have dozens of data products actively integrated systems.

That requires serving layer that is robust, agile, flexible, and allows for self-service. Models produced on Flotilla are packaged for deployment in production using Khan, another framework we've developed internally. Khan provides our data scientists the ability to quickly productionize those models they've developed with open source frameworks in Python 3 e.

This provides our data scientist a one-click method of getting from their algorithms to production. DataScience DataStack Data.

Understanding When to use RabbitMQ or Apache Kafka

If you can think in queues then RabbitMQ should be a viable solution for integrating disparate systems.The message broker supports the telecommunication system by helping the computer to interact with each other by sharing the defined messages to various applications. It executes a broker architecture where the messages are queued on the central nodes before sending them to the destination.

ActiveMQ works on middle ground and deployed with a broker and P2P architecture. It is known as the swiss army knife of messaging. ActiveMQ holds Apache License 2. RabbitMQ works based on the center which makes this a unique approach.

RabbitMQ is very portable and user-friendly. Because the huge actions such as load balancing or persistent message queuing runs only on a limited line of code. But this approach is less scalable and slow because of its latency addition from the central node and size of the message envelope.

ActiveMQ is easier to implement and provides advanced features such as clustering, caching, logging and message storage. RabbitMQ is embedded in applications and acts as midway services. It differentiates support encryption, storing data in the disk as pre-planned in case of an outage, making of clusters, duplication of services to have high reliability.

It is deployed on the OTP platform that assures maximum scalability and stability of the queue that acts as a key node of the entire system. ActiveMQ comprises of Java Message Service client which has the ability to supports multiple clients or servers.

The attributes like computer clustering support the ActiveMQ to manage the communication system. Some of the features of RabbitMQ are rapid synchronous messaging, advanced tools and plugin, distributed deployment, developer-friendly, and centralized management.

Here there is a separate network of brokers allotted for distribution load. ActiveMQ Artemis gives an amazing performance and deployed in non-blocking architecture for event flow of messaging applications with 1. It has an adaptable clustering for distributing the load. It is a powerful addressing method that provides easy migration. RabbitMQ has many advantages that support multiple messaging protocols, delivering acknowledgment and message queue.

It is enabled with various languages such as Python. NET, and Java. It can also make the developer use applications such as Chef, Docker, and Puppet. It gives high throughput and availability by developing possible clusters.

It can easily handle the public and private cloud by the support of pluggable authentication and authorization. ActiveMQ has multiple advantages that can be applied to have high efficiency according to the requirement.

It also programmed to manage IoT devices. RabbitMQ admin-browser works on the user interface. It is freely available. Methods of synchronization It is configured with the synchronous method but it can be modified into asynchronous by modifying the setting panel.RabbitMQ is one of the most widely used open-source message brokers.

It is written in Erlang. Redis is an open-source in-memory data source which can function as a message-broker, database, and a cache. It supports various data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes with radius queries and streams.

It is quite fast and light-weight. Here we will discuss the top 9 difference between RabbitMQ vs Redis which are explained in detail. Redis is a database that can be used as a message-broker.

On the other hand, RabbitMQ has been designed as a dedicated message-broker. RabbitMQ outperforms Redis as a message-broker in most scenarios. RabbitMQ guarantees message delivery. This is achieved by:. RabbitMQ supports persistent messages in addition to transition ones. The RabbitMQ persistence layer is meant for providing reasonably high throughput in most of the situations without configuration.

RabbitMQ allows you to use an additional layer of security by using SSL certificates to encrypt your data. Secure Sockets Layer SSL is one of the most popular security technology for establishing an encrypted connection between a server and a client.

Redis, on the other hand, does not support SSL natively and in order to enable SSL, you have to opt for a paid service. Redis recommends using Spiped for encrypting messages. Spiped is a tool for creating symmetrically encrypted and authenticated pipes between socket addresses, which would enable us to connect to one address e. It is a dedicated message-broker. It is widely used in implementations of highly centralized and distributed systems. It is very important to choose a message broker depending on your use case.

As Redis provides extremely fast service and in-memory capabilities, you should prefer it for short retention of messages where persistence is not so important. On the other hand, you would prefer RabbitMQ when there is a requirement for complex routing. This is a guide to RabbitMQ vs Redis.

Here we discuss the RabbitMQ vs Redis introduction, key differences with infographics and comparison table.
