Globally In-Memory Shared Variable Operation

[brad302]

I think the idea of a globally shared in-memory variable would be a handy addition to the LogicApps framework.

I've used Service Fabric in times gone by and such a feature existed which made life a lot easier when needing to reference a relatively small element of information that could change minute on minute if not second on second. The important part to note is that the variable is replicated across all of the running nodes.

Updating environment variables is obviously not as efficient given they then require the app to restart in order to take effect.

So as an example, I have another set of Azure Functions instances that have the ability to scale up and down on a relatively regular basis (given the constraints) and I want to store some data on the status of those instances so other running workflows can access that data. At present, I'm able to achieve that using something like Azure Storage Tables that but my concern is that the amount of executions I'm running at anytime may start to throttle the storage account where those values are housed.

That's the basic thinking.
