If Dgraph uses the bulk loader, does it mean that scaling is not possible? Based on my understanding of the code, the w directory is used to record write-ahead logs (WAL). When a new node joins, synchronization is performed through sequential writes based on snapshots in the w directory. However, in…

That’s correct. Bulk loading is intended for the initial creation of the graph, not batch updating. Check out the “live loader” for that use case.
