I had started working on a Kanban tool with Elixir and Dgraph, but I could not continue due to time and Dgraph taking a different direction (focusing more on its role as a GraphQL API provider than a DBMS), never tried any other graph databases, this book may give a good overview on different graph db and state of their Elixir libs. The chapter on GraphQL isn’t out yet, I’d be very interested to find out the author’s take on that.
Anyways, bought the book and started reading, like all other PragProg Elixir products, this too is awesome.
