About Cassandra. I understand that it’s not a relational DB but noSQL. Although the Dgraph is noSQL, it can be relational between nodes. I also believe that Cassandra is not ACID, since the Dgraph is. There is no default hierarchy in Dgraph and there are transactions thing that there is not in Cassandra.
I personally (as a DB user) do not know much about Cassandra, but I know it’s different from Dgraph. You may be comparing the idea of replication and clustering. In that case there are features of Cassandra that resemble each other.
And yes, Dgraph can handle an absurd amount of data in a distributed way.
