How to Migrate Data From Neo4j to Nebula GraphCategory: Database, Data
This article mainly introduces how to migrate your data from Neo4j to Nebula Graph with Nebula Graph Exchange (or Exchange for short), a data migration tool backed by the Nebula Graph team.
The name of our data migration tool is Nebula Graph Exchange.
After transforming data into a DataFrame, Nebula Graph Exchange traverses each row in the DataFrame, obtain the corresponding values by column names according to the fields mapping relationship in the configuration file.
The procedure is demonstrated in the following picture: We use the following system environment to demonstrate the import here: Hardware: Software: Since Nebula Graph is a strongly-typed schema database, you need to create a space, tags, and edges types before importing data.
Since the data importing to Nebula Graph is parallel, we don’t guarantee that the final data is the latest data in Neo4j.
