Okay, I’m not sure what you didn’t understand. What is your level of Dgraph? are you a pro Dgraph user? new? So I can elaborate a didactic answer or just say what would be the way.
Dgraph doesn’t have any “start from this point” feature. There are “advanced” ways of doing it that you have to master.
For example XID
dgraph bulk -h | grep xid
--store_xids Generate an xid edge for each node.
--xidmap string Directory to store xid to uid mapping
It is a complex topic, but once you get it you can go really far on mastering Dgraph.
You can also use the XID technic in live loader after the bulk - you just need to maintain unique Blanks nodes over your whole env.
➜ ~ dgraph live -h | grep xid
-U, --upsertPredicate string run in upsertPredicate mode. the value would be used to store blank nodes as an xid
-x, --xidmap string Directory to store xid to uid mapping
Also, there is the new upsert predicate. Which is a new feature that creates a bunch of upsert blocks based on your data. It is a new way but also valid.
The main suggestion I gave to you before was to have UIDs on your data. But I don’t know if your data comes from Dgraph, or is from another DB or something. Deal with the UID yourself is a hard job. But it is a way.
This is the way.
