Blank nodes in mutations, written _:identifier, identify nodes within a mutation. Dgraph creates a UID identifying each blank node and returns the created UIDs as the mutation result.
How the Uids been created , if i have a cluster different node will conflict during create Uids? so the uid assign is related to different cluster node ?
another question what’s the key like stored int the Badger , can some one give me a demo to show the struct of key in the Badger , if you can give me a value stored in Badger that will be better
