Hi,

We need to use ActiveMQ as backplane, but I'm not sure if this project is still active, or if you know of any issues with this solution.

One of our concerns is to make sure the connection is still active, and to react when the connection changes its status (via event or delegate). Do you recommend to use this version on production?

I don't recommend this solution. Signalr requires a distributed incrementing sequence number to know if a message has already been received or not. While this project will work as a backplane, you will most likely receive some messages multiple times since Activemq doesn't have a sequence number for its messages.

Thanks Chris. Didn't know about that.

I saw you also contributed to SignalR.RabbitMQ. Currently we need a backplane for our MVC5 app which runs under a load balancer (4 servers), so we can use it with signalR, but unfortunately we have two restrictions:

  1. Our client don't want to use external services like Azure, for security reasons
  2. They are OK with anything related to MS technologies, or something that can run under Windows. There is a Redis for Windows from 2016, but we have duplication of messages. That bug does not happen with the latest version (tested under Linux), but unfortunately that's not an option for us.

Based on your experience, do you have any recommendation? looks like the official signalR message bus only support Redis (linux) and Service Bus (azure). That's why I found your project, as ActiveMQ runs under Java. What about Rabbit, or any other solution for MS servers?

Thanks in advance!

The Rabbit one works. That project includes a Rabbit plugin that injects a sequence number. We didn't want to have to install a Rabbit plugin so I created a project based on that, that still uses Rabbit, but uses MongoDB to manage the sequence number. That has worked well for us.

Apparently the readme is wrong so here is the Nuget package:
