New Features in Oracle Graph Server and Client 25.1

Features That Work With Oracle Database Release 23ai and Prior Oracle Database Releases

• Added support for configuring the graph server (PGX) using a quick setup script.

  See Configuring the Graph Server Using a Quick Setup Script for more information.

• Added support for creating partitioned graphs using the GraphBuilder API.

  See Creating a Partitioned Graph Using the GraphBuilder Interface for more information.

• Progress tracking support for graph algorithms is extended to include more built-in graph algorithms.

  See Getting the Progress of a Running Algorithm for more information.

• Added Bellman-Ford Single Source Single Destination built-in graph algorithm. Bellman-Ford is a fast algorithm designed for finding a shortest path in a graph. This new variant of Bellman-Ford's algorithm attempts to find the shortest path (if there is one) from a single source to a single destination, while minimizing the distance or cost associated to each edge in the graph.
• Added support for import and exporting the Graph Visualization settings as a JSON file.

  See Importing and Exporting Graph Visualization Settings for more information.

• Added support for managing both default and custom styling of vertices and edges in the Styles tab of the Graph Visualization settings.

  See Configuring Vertex and Edge Styles for more information.

• Added support for enabling the cluster option with Force layout to visualize a graph by grouping vertices.

  See Enabling Cluster Option in Graph Visualization for more information.
