Does it make sense to use REDIS instead of shared variables

[infinitenothing]

I feel like REDIS accomplishes most of the goals that shared variables attempt to cover (minus some UI sugar) in a nice cross platform way. Does anyone have an opinion on "in memory" key-value stores that are accessible over a network?

For those ignorant as me, https://redis.io/ .
Given the shame that shared network variables are, I would tend to say that any other solution, no matter how much of a contraption, might be attractive. I'm curious to read opinions too, as well as ideas for a LV API.

I do. REDIS is great. It's much nicer to work with than shared variables or OPC. The downsides I can think of are:

1) You need a Linux server or Windows new enough to have WSL2 to run the server. There is no official Windows build

2) The protocol is simple, but the API is pretty big. I don't know if anyone has created a publicly available LabVIEW client. You can put together a client library with only the most common commands pretty quickly though.
