Comparison of methods for importing data in batches into Neo4j.

Methods	Running speed	Advantage	Disadvantage	Scope of application
CREATE	Slow (1 k nodes/s)	The statement is simple, easy to use and understand and can realize the real-time insertion of new data	Slow speed	1 − 1 w nodes
LOAD CSV	General (5 k nodes/s)	In addition to the advantages described in the CREATE, you can load not only local CSV, but also remote CSV	The data must be converted to CSV	1 w − 10 w nodes
Neo4j import	Fast (tens of thousands of nodes/s)	The data import speed is fast and the running time is short	Neo4j must be disabled during the import process; you cannot reimport new data using import in an established database	Over ten million nodes
