Concurrent writes to Neo4j -

i have instance of neo4j running remotely (it's in azure vm)

i have large amount of data want populate graph with: 1m nodes, each of may have ~100 relationships.

if add these local machine, can add around 1000 nodes per hour i.e take thousand hours populate graph.

i distribute uploading e.g. running number of azure workers push data neo in parallel.

my question is: neo able handle this? particularly, single node may have new relationships nodes not yet created, , create them - create operations using cypher merge.

if neo happy this, great. if not, there frameworks / best practices help?
