What’s New With Neo4j Data Importer (July 2022)

19 Jul, 2022



This release of Data Importer brings you a new capability to ‘Preview’ your graph. The new ‘Preview’ button, available immediately next to ‘Run Import’, will quickly approximate what a subset of your graph looks like. Chapters: 0:00 – Intro to Data Importer 0:56 – Getting started 1:24 – Add flat files to Data Importer 2:05 – Data Modeling 6:03 – Previewing the Data Model 7:19 – Run the import and review results 7:43 – Querying the data 8:15 – BONUS example dataset To keep the ‘Preview’ as performant as possible, we’ve made some optimizations you should be aware of so you understand the subtleties of what you see: – It uses the first few rows of the files associated with relationships to preview up to 300 relationships in total. If the most linked parts of your graph aren’t towards the top of each file, you may not see the depth of connections that materialize in the fuller load. – We don’t currently preview the properties you have mapped to nodes. We show the columns mapped to IDs in the relationships as node properties. So don’t worry if you don’t see the properties you have mapped. – We currently only preview relationships and their linked nodes. If you have an isolated node in your model or one that doesn’t yet have a fully mapped relationship, you won’t see it in the preview. But we’re working to fill that gap in a future release. We hope this new feature helps you iterate more quickly, testing out ideas before committing to a full load. You’ll also notice there have been a few styling changes and minor bug fixes trickling through to make Data Importer tidier and more pleasant. Visit neo4j.com/aura to learn more
