Hi, @David McKee Before contributing a use case. Frist of all, I loved your talk, I loved your introduction of a cloud environment for digital twin that will be available for everyone.
I noticed you are using a “unified graph-based structure” – that underpins common geospatial reference, does it mean a graph database, do you mind expanding on this? What technology are you using? How scalable is it?
Very good question, we still ponder over this once a week! The tradeoff is graph datastructre vs timeseries datastructure and the sheer scale of the data that can be generated and may need to be processed in real-time. Our experience is to use a mroe traditional horizontally scaling SQL database with the support of tools such as Apache Spark. This also helps with interoperability using the likes of Apache Pig.
Happy to dive into more detail.
