HI I am working in one is called omniql, I am lone developer, so probably it will take time, but there are much of the what they said in the book planned for omniql, is based in observable pattern so it will have live queries by default, it will use system like kafka, nats, Redis or any message system, for communicate the partitions of the distributed databases and do computation that can be merged hierarchically, the computation are done by `serverless function` in any language, is a model that can be extended to ui interface to and create a framework very similar to mobx , but more lightwave, and ui components that can automatically query their data requirement to the server just when they are observed, I am creating a binary protocol of communication for this called delta https://github.com/nebtex/delta, that is perfect for this system an incremental computing, is a really a big project, but I hope to have something working for the next 6 months.
