This is great from a data storage perspective, but i've always struggled to figure out the best approach for utilizing multiple regions to comply with legal issues like this. That brings me to my question: How do you store your data so that you comply with the laws of a country, when you actually export your product to several countries? Having multiple instances of your system seems impractical and sharding data by country across regions could be rather hard. I.e. I am in Canada, we have US clients who desire their data to be in the US and Canadians who want it in Canada. Either we add complexity or someone doesn't get what they want.
