No, it's a bad idea.

Thanks for your interesting POV on the Redis/Kafka intersection on this. In any case, this shouldn't have an impact on the Disque roadmap significantly IMHO. If you never tried Redis Streams, even if you plan to go with Kafka in production, I suggest you try prototyping your application with Redis Streams, as it literally takes a couple of minutes to get up and running on your laptop. Why? It's just much more work to install and maintain Kafka, and it has issues with load balancing and recovery due to the design tying cluster ownership to partition data. But here's the deal - every time I had to rely on Redis as a critical component, there was a problem. The Redis database to connect to. Brokered means that participants connect to the same service, which acts, as the name suggests, as a central broker to implement the whole message-routing mechanism. A great choice for fast, set-based operations. Here we end our journey through the self-deploy messaging systems. Albeit my request is quite selfish, I really would love to hear/read more about your thoughts on designing APIs. Alas, I have been more than once bitten by poorly implemented GIL and in my personal experience any GIL is problematic in a high-throughput environment. Even if the client app is temporarily unavailable (suddenly added to the system, or changed), the messaging process isn't interrupted or stopped. RabbitMQ defaults to the former behavior while Redis Pub/Sub focuses on just doing the bare minimum amount of work for fire-and-forget. Why I'm choosing to go for integer numbers? If you enjoy talking about TCP connections on steroids and streaming architectures, feel free to reach me on Twitter @croloris. These kinds of APIs seem to have fallen out of fashion, though. Next time you need to connect two services together, this should help you navigate your options.

I've tried using Apache Kafka and it can be a bear to set up given its dependencies and to administer. Would I use memcached-db? Which will blow your mind. At that point, you have two main options: brokerless or brokered tools. Could someone ELI5 what's a redis stream ? How is this going to be different from Kafka? And that's a great idea and not that many services let you model datastructures in a distributed way. Compare Apache Kafka vs Redis. Note: You should know that "redis-cli" won't accept any commands once in subscribed mode. In this context, synchronous means that all parties need to be active at the same time to be able to communicate. Streams back ported to 4.0 (Work in progress) ->. OTOH, I believe that implementing Disque will have implications on the Modules API, so these would have to be backported to a v4.2 (or alike) if it is decided so. Previously, he spent several years at Yahoo building database replication systems and multitenant messaging platforms. A comma separated list of Redis hosts to connect to. For example, sensor readings or logs contain values that by nature are indexed by creation time and are append-only (you can’t change the past). Can't we get a super reliable data store that supports data structures? The high price of the most popular messaging tools of those times. The resolution could be made to be accepted in milliseconds, and it should be simple to honor it with an error for example of 50 milliseconds or alike, but to get true 1 ms resolution requires non trivial changes to the system that must act like a real time scheduler in some way... Love that you are using sem version properly. Great to see. Let’s consider a few examples to see which problems are best solved by each pattern. RSMQ: A lightweight message queue for Node.js that requires no dedicated queue server. The batch size of write to Redis database. My company (https://fanout.io) has built tools to help with this. In this article, I will guide you through the defining characteristics of various communication patterns, and I’ll briefly introduce the most popular tools used to implement each. The Redis operation time in milliseconds.

It was hosted by the CodeHaus. Developers describe Disque as "In-memory, distributed job queue".

We will consider the pros and cons of ActiveMQ and Redis Pub/Sub. Either there was that "one gotcha" in the config or I didn't understood something or else. The message broker is based on the JMS API. Here's another problem Redis geniousl added: a GIL. They are rightfully described as “TCP sockets on steroids.” In practice, you import the library into your code and use it to instantiate a connection that can employ various built-in message routing mechanisms, such as Pub/Sub, Push/Pull, Dealer/Router, etc. At the beginning of ActiveMQ development, there were two reasons to start out the project: Unlike its competitors (EMS/TIBCO, SonicMQ, WebSphereMQ), the messaging system combined accessibility with useful and effective features. Maybe there's room for both products in the market? Redis offers a real Pub/Sub fire-and-forget system, as well as a real Stream data type. In practice, these message inboxes are like task queues. From the blog post, it sounds like the RDB format will break. It's especially suitable for enterprise projects.
