Full disclosure I work at MSFT and on the fluid framework. If you are interested in this you may also be interested in the fluid framework, https://github.com/microsoft/FluidFramework We use websockets and solve a lot of the state management problem called out here by keeping very little state on the server itself. The primary thing on server is a monotonically increasing integer we use to stamp messages, this gives us total order broadcast which we then build upon: https://en.m.wikipedia.org/wiki/Atomic_broadcast Here are some code pointers if you want to take a look: The map package is a decent place to look for how we leverage total order broadcast to keep clients in sync in our distributed data structures: https://github.com/microsoft/FluidFramework/blob/main/packag...

ge the websocket. It also hits storage to give the rest of the system a continuous, ordered stream of events: https://github.com/microsoft/FluidFramework/blob/main/packag... The main server logic is in the Alfred and Deli lambdas. Alfred sits on the socket and dumps message into Kafka. Deli sits on the Kafka queue, stamps messages, the puts them on another queue for Alfred’s to broadcast: https://github.com/microsoft/FluidFramework/tree/main/server...

(Disclosure: Work at Microsoft, but I work in Azure and some open source stuff, not on or directly with Fluid/Office/etc.) That's just a trademark clause for Microsoft logos and brands. The Fluid Framework itself is MIT licensed [0] and doesn't require exposing any of those logos/brands when you use it, so the framework itself is fairly open for usage. I think the main thing that would slow down adoption for Fluid is that the only "production" backend is an Azure service, which isn't part of the open source Fluid Framework. Other open source backends[1] aren't recommended for productions. Until there are some open source ones, I'd assume adoption will be limited to folks in the Azure ecosystem.

In Microsoft Loop brings back Google Wave?
Has anyone tried to develop anything with MSFT's Fluid Framework [1], which is used to build Loop? I have not got a chance to check details. But it seems quite nice. Any general remarks are welcome. Particularly, I'm interested in understanding customizability of Fluid components, integration with React, and any concerns about Azure service lock-in.

In Microsoft Loop brings back Google Wave?
Disclosure: I work on a related project (Fluid Framework) that makes application agnostic CRDTs easily available. The CKEditor folks did a great job building an OSS text editor and they did an especially strong work building a text editor that works well with collaboration. I've made a few OSS rich text editors work (mostly) with Fluid [0, 1] and the design of the text editor really changes how easily collaboration can be added. Luckily the text editor accepts remote changes, integrating an OT or CRDT solution is approximately the same. They also did a great job explaining the problem. My experience has been that people don't intuitively understand why real time collaboration is a tricky problem. I didn't. First of all, for a bunch of use cases websockets + redis + a last write wins conflict resolution (or some similar solution) is totall

y enough. Second, it's not immediately obvious why rich text editing requires more complex conflict resolution. Third, it's not obvious why solving the RTE problem doesn't immediately lend itself to other problems [2]. Because we started building in mid-late 2017, right as CRDTs really started to get competitive with OT, we chose a CRDT approach, but the collab problem space in general is much deeper I realized before getting into it. Anyway, I always appreciate seeing people explain their journey. Especially when it has to do with collaboration. [0] https://fluidframework.com/playground/?path=/docs/react-demo...
