2.7.0

neo4j-graph-data-science-2.7.0

Breaking changes

• Removed support for Neo4j DBMS v4.

New features

• A new parameter targetNodes has been introduced to gds.shortestPath.dijkstra procedures that allows specifying multiple targets rather than a single target.
• GDS Arrow to database import now also supports creating database with block storage engine. This requires at least Neo4j 5.18.
• gds.graph.export now supports setting a database format using the dbFormat key. See https://neo4j.com/docs/operations-manual/current/database-internals/store-formats/ for supported formats (block requires at lest Neo4j 5.18).
• Added a dedicated Arrow export command to extract node labels from an in-memory graph.
• Arrow graph export commands support exporting node identifiers mapped to a consecutive id space, i.e. [0..nodeCount).
• Add support for DBMS V5.21.0

Bug fixes

• Fixed a bug where the batch size configured in arrow stream messages would be ignored
• Fixed a bug where graphs could be projected with empty name when using Cypher projections v2.

Improvements

• Writing relationships can now be done in parallel, the concurrency can be controlled by the writeConcurrency parameter.
• Progress logging for Closeness centrality is more detailed.

Other changes

• The record_format field in the GDS Arrow Create Database action is deprecated for removal, use db_format instead.
