Missing some context and explanation about difference / complementary vs dgraph bulk or live.
I don't know myself but it should be something like
"""dgraph import command has been introduced in v25.0 (?) to simplify the import of data generated by dgraph bulk load."""
Then a small explanation of the improvement.
""" Dgraph bulk previous process consisted in stopping alpha, copying p files at the righ places, restarting alpha ...""
dgraph import dramatically simplifies those steps. You don't have to stop the alpha nodes and dont't have to deal with copying files. Simply invoke dgraph import --snapshot-dir ... explain the command".
The second use case (import RDF) -> is it a replacement of dgraph live or an alternative / need to identify in which case I would need to use dgraph live (network constraint ?). Is there a performance difference ?
So I would describe snapshot first (bulk load output importer) and RDF/JSON file second.
