Graph Studio Version 2025.0

This section describes the new features, improvements, and fixes in Graph Studio Version 2025.0.

New Features

Improvements

Product Rebranding

For version 2025.0, Anzo has been rebranded as Altair® Graph Studio™, and AnzoGraph has been rebranded as Altair® Graph Lakehouse™.

Altair Units Licensing

Version 2025.0 introduces Altair Units Licensing - a value-based license management system enabling metered usage of Graph Studio and all other Altair products. Graph Studio and Graph Lakehouse belong to the Altair Data Analyst suite of applications of the Altair RapidMiner Platform, all of which have the capability to use a single pool of recyclable Altair Units. The license units consumption of Graph Lakehouse depends on the CPU resources (the number of CPU cores) on the host system. As of this version, Graph Lakehouse consumes 6 units per core.

Note: Even though the slices_per_node setting is used by Graph Lakehouse for runtime behavior, it does not affect the license units draw, which depends only on the total number of CPU cores on the host hardware.

Cambridge Semantics license keys are still supported as a legacy licensing method to ease the transition to the new licensing system for existing customers.

Vault for Credentials

Version 2025.0 supports integration with HashiCorp® Vault to keep and encrypt credentials for increased security. Administrators can safely share connections without exposing credentials.

Integration with Keycloak for Authentication

Version 2025.0 supports integration with the Keycloak standard for improved authentication, which provides additional trust and numerous features like credential constraints, two-factor authentication, and many others.

Mapping Tool

Version 2025.0 introduces a mapping tool in the Data Layer interface, which allows the user to map nodes and properties for easier management of data and ontologies. The mapping tool improves usability and provides easier management of ontologies and data.

Context Attribute Step

Version 2025.0 introduces the Context Attribute Step, which allows the user to define and run a SELECT query against a graphmart, Graph Lakehouse, or another data source, a system journal or a semantic service, so that the named variables from the first row of the query result get inserted as context attributes into the graphmart. This provides the means to introduce logic for conditional execution of steps and layers, as well as custom incremental logic. Furthermore, for all step types that involve a query, the query templates within steps and views can use context attributes as template replacements before being sent to Graph Studio.

Write Back Step

Version 2025.0 introduces the Write Back Step, which allows the user to write an update query against Graph Lakehouse, but use a different datasource as the target of the update, writing information back into another datasource or activation metrics graphs, or calling a semantic service with data from the query.

Validate Data Step (with SHACL Shapes Validator)

Version 2025.0 introduces the Validate Data Step to check data consistency by running a SHACL shape validator on Graph Lakehouse. This step runs SHACL validation against the shapes in the graphs specified by the user. The step interface also allows the user to choose what to do if the validation fails: mark the data layer load as failed or mark the entire graphmart load as failed.

Support for Kubernetes Deployments

Version 2025.0 supports deployments on Kubernetes with containerization and K8s-style upgrades. Tested on Amazon EKS, Google Kubernetes Engine (GKE), and Microsoft Azure Kubernetes Service (AKS).

FIPS Compliance

Version 2025.0 is compliant with FIPS crypto policies regulations.

Graphmart-Centered UI for Improved Usability

Version 2025.0 introduces new, improved user interface centered on the graphmart instead of the flow with separate onboarding, model, etc. The new graphmart-centered interface is clearer, easier to understand, and provides a shorter learning curve.

Connections in Graphmarts

In Version 2025.0, connections are objects that can be generated via user interface in Graphmarts. This simplifies the creation and configuration of connections.
