将数据从 RDBMS 迁移到 Arango DB：批量上传

Question

Iam trying to move data from RDBMS to ArangoDB. I wanted to know if there are any tools for transforming the RDBMS data to collections and edges to do a bulk upload to ArangoDB. I could also see that ArangoDB bulk upload API allows only one type of collection to be uploaded at a time. Is there anyway to upload collections and edges at the same time?

Answer 1

The only way to upload both at the same time would be to run multiple instances of your import program/script (eg arangoimport or JavaScript/Python/PowersHell script). But realistically, there aren't many situations when you need to do this simultaneously, and attempting to do so might cause problems).

As for data transformation, that is a different topic, and the answer depends wholly on your level of comfort with various technologies. Personally, I use several tools but mainly rely on Pentaho Data Integration ( info and download ) to export data and JS and Python scripts to import, leveraging the ArangoDB API.

Because DB platform transition is SO individualized, you won't find a tool to quickly do this, especially when you're moving from RDBMS to document/graph. Normalization requirements between the two can be quite different, usually requiring you to re-work the data model.
