Re: CRDTs and intuition, yup, there's trade offs. We are working hard to deliver a solid model to code against. So we have finality of local writes and standard relational integrity guarantees. You can read a bit more about some of techniques here https://electric-sql.com/blog/2022/05/03/introducing-rich-cr...
Re: electrify yes, we create a shadow table and some operation log tables etc. So there is some storage amplification but it's of the order of 2x (we use operational based CRDTs and we garbage collect the operation log). We see the fit being with standard OLTP workloads, mainstream relational apps. We don't target high volume data ingestion, etc.
Re: commercial model, we're designed for open source self-host. We see Electric as a drop in sync layer, not as a full stack backend-as-a-service. Lots of options but concentrating on product for now.
