What if you can read & write to your database locally from multiple locations and each location has all the data with various consistency guarantees?
Most of the current generation databases cannot be used like a CDN spread around several regions (10s, 100s) across the globe providing local read-write latencies. CRDTs are a promising technology that can enable this. My guess is in next 2-3 years more companies will build data platforms that leverage CRDTs underneath and build coordination-free systems like Macrometa fast data platform.
You can use the below repl.it to see in action where there are reads-n-writes from each region locally and all regions get all the data locally.
I would like to hear your thoughts on what would be a good demo app / killer app for this platform. Any suggestions?
