It is done just for this, to initialize an ingest from scratch.
In that case either you use a client or via LiveLoad.
is simple, BulkLoad creates the output folder “Out/*” each new folder with a number would be a Shard. You can control this by editing the flag “--reduce_shards”. Once you have a output done, just get those files in “out/0/*” and move to a Dgraph Server from scratch. And run your server.
Or copy the Dgraph binarie to that path and start Dgraph Server from there.
