Benchmarks of dgraph, cassandra, aws neptune, tigergraph, neo4j would be nice, but also a TCO. tigergraph cost more on aws than neptune, so is it worth the price? Dgraph starter is USD9750 per node per year, maybe running more aws neptune nodes is better. A ten ton truck is better than a six ton truck, unless the six ton truck has half the TCO. Benchmarks are nice, but not the bottom line.
