A.f.a.i.k the name is based on the underlying library and research on Dfferential Dataflow by F. McSherry https://www.microsoft.com/en-us/research/publication/differe... and https://timelydataflow.github.io/differential-dataflow/ ... I think the pitch is that this concept is enough improvement on incremental approaches it warrants a new name.
But I love these. From Functional Reactive Programming through propagator networks and embedding functional languages in datalog datafun-style, there seems to be this new-ish approach to computation that maybe somebody finally cleaves out of academia! The eve-lang guys were close but too ambitious. Maybe VMWare has less ambitious, more focused tool in mind.
Because datalogs are so cool! But only time I see them in practice are bespoke implementations for like ... compiler optimization tuning?
