6.1.0

What's Changed

Tip

This minor release bump is fully API compatible with 6.0.1, we bumped the version for two reasons:
The virtual column element_id has been renamed to v$id and consistently shows now in the database metadata as "generated column". The naming has been chosen on purpose to avoid any clash with nodes that have an actual property of that name (No, the elementId() of a node is a function call, just like id() was, it is not a property).
The second reason is for the fix in behaviour of executeUpdate which now returns the estimated number of updated rows instead of the cumulative updates in a statement. This is in align with the JDBC Spec.

The most exciting new feature of this release is the introduction of virtual tables for relationships. The metadata does now some sampling of the graph (Similar to what is done in the schema introspection PoC or Apoc Meta) and lists relationships between labels as label1_TYPE_label2 in the data dictionary, with a v$id column for the relationship, and v$label1_id and v$label2_id so that ETL tools can actual join those with the labels.

Those virtual tables are fully queryable, so that you can do a SELECT * FROM Person_ACTED_IN_Movie, which will return the element ids of the relationship and the start and end nodes and all relationship properties and they do partake of course proper in joins.

Using the standard JOIN syntax, the driver will translate the query to a simple pattern match, so that

SELECT p."v$person_id", name, title, roles 
FROM Person p
JOIN Person_ACTED_IN_Movie pm ON pm.v$person_id = p.v$id
JOIN Movie m ON m.v$id = pm.v$movie_id 
WHERE title = 'The Matrix'
ORDER BY title, name

becomes

MATCH (p:Person) -[r:ACTED_IN]->(m:Movie)
WHERE m.title = 'The Matrix'
RETURN elementId(p), p.name AS name, m.title AS title, r.roles AS roles
ORDER BY m.title, p.name

When you enumerate the tables in the FROM clause and join inside WHERE, the driver will match start and end nodes separately and then join on ids as well. We might change this in a future optimisation.

6.0.0-M02

What's Changed

The second milestone includes several important updates, among them the fact that we now ship a BOM module, which makes it really easy to import all artifacts of the driver in a consistent way in any Maven or Gradle build.

Also we would like to highlight the fact that we now can

• chain SQL translators
• use INSERT..RETURNING statements, that will automatically be translated to Cypher
• use character and binary streams as well as big decimals for prepared statements
• propagate readyOnly correctly into the Bolt layer

While you can always use a modern Java 8+ time type, we aligned the classic way of using java.sql.Date and java.sql.Time and the corresponding methods on the prepared statement and results that take in an additional Calendar instance for building timezone information with the way dates, times and date times work in Neo4j.

Additionally, we tested the binaries we have now with more tooling. We have been able to successfully use the driver within:

• DBeaver
• IntelliJ DataGrip
• KNime
• Apache Nifi
• Tableau

6.0.0-M01

This is the first milestone release of the Neo4j JDBC Driver version 6 with exciting new features:

• It does not depend on the common Neo4j Java driver anymore, thus being less resource intensive
• It provides a pluggable SQL to Cypher translation infrastructure and comes with one implementation ootb
• Better support for the JDBC Metadata APIs

The Java baseline for this version is JDK 17.

Please have a look at our documentation for information how to migrate from version 5 and 4: Migrating from older versions of the driver
