Gearman vs RSMQ: What are the differences?
Gearman: A generic application framework to farm out work to other machines or processes. Gearman allows you to do work in parallel, to load balance processing, and to call functions between languages. It can be used in a variety of applications, from high-availability web sites to the transport of database replication events; RSMQ: A lightweight message queue for Node.js that requires no dedicated queue server. Just a Redis server. tl;dr: If you run a Redis server and currently use Amazon SQS or a similar message queue you might as well use this fast little replacement. Using a shared Redis server multiple Node.js processes can send / receive messages.
Gearman and RSMQ can be primarily classified as "Message Queue" tools.
Some of the features offered by Gearman are:
- Open Source It’s free! (in both meanings of the word) Gearman has an active open source community that is easy to get involved with if you need help or want to contribute. Worried about licensing? Gearman is BSD
- Multi-language - There are interfaces for a number of languages, and this list is growing. You also have the option to write heterogeneous applications with clients submitting work in one language and workers performing that work in another
- Flexible - You are not tied to any specific design pattern. You can quickly put together distributed applications using any model you choose, one of those options being Map/Reduce
On the other hand, RSMQ provides the following key features:
- Guaranteed delivery of a message to exactly one recipient within a messages visibility timeout.
- Received messages that are not deleted will reappear after the visibility timeout.
RSMQ is an open source tool with 1.07K GitHub stars and 78 GitHub forks. Here's a link to RSMQ's open source repository on GitHub.
