Graph Lakehouse 2026.0 Database 3.3 Releases

To view the release notes for a Graph Lakehouse database 3.3.x release, select the version from the list below. The release notes for each version describe the product changes from the previous version.

• Graph Lakehouse Database Version 3.3.1
• Graph Lakehouse Database Version 3.3.0

Graph Lakehouse Database Version 3.3.1

This section describes the improvements and fixes in Graph Lakehouse database v3.3.1.

This version includes patches for identified security vulnerabilities. For details about these patches, see Patched Vulnerabilities.

Improvements

• Implementation of a Database-Enforced Timeout Mechanism - Version 3.3.1 introduces a timeout mechanism that forces long-running queries to abort, thereby freeing up resources for other database operations. The setting query_timeout, if specified in the settings.conf file, specifies the number of minutes that can elapse before a query times out. Alternatively, the timeout value can also be specified on a per-query basis by prefixing the query with set query_timeout=20;;.

Fixes

• Legacy Cambridge Semantics licenses cannot be validated using OpenSSL 3.5 - Version 3.3.1 resolves previous issues with validating legacy Cambridge Semantics licenses using OpenSSL 3.5.

• Confusing error messages - In Version 3.3.1, the confusing error message "Element larger than allowed unknownIRI - too many properties" has been revised to "Cannot add more than 255 RDF* properties on a triple" to enable better understanding of the error.

Graph Lakehouse Database Version 3.3.0

This section describes the fixes and improvements in Graph Lakehouse database v3.3.0.

This version includes patches for identified security vulnerabilities. For details about these patches, see Patched Vulnerabilities.

New Features and Improvements

• Support for the Louvain Method and Leiden Algorithm as User-Defined Extensions
• Support for Specifying a Destination Vertex in Unweighted Graphs
• Support for Stream-Based Unions
• Support for the Use of a UDP in a USING Clause for SELECT and INSERT Statements

Fixes

• Graph LakeHouse Crashes While Running ES Index Query
• Numeric Overflow When Calculating Date/Time Deltas for Values Far from the Epoch
• Invalid Results when Running a Query with Multiple Options/Clauses/Bindings

Support for the Louvain Method and Leiden Algorithm as User-Defined Extensions

Version 3.3.0 adds support for the Louvain method and Leiden algorithm as user-defined extensions. When registered and loaded into the Anzograph system, they can be used within queries or other command statements, enabling better cluster detection in large networks.

Support for Specifying a Destination Vertex in Unweighted Graphs

Version 3.3.0 enables users to specify a destination vertex in unweighted graphs, thereby improving performance and computation efficiency when using the shortest path function.

Support for Stream-Based Unions

Version 3.3.0 introduces support for stream-based unions. In this type of union, the results of each producing leg are computed and shared to the consuming section via an inter-process communication queue, resulting in improved efficiency and responsiveness when executing certain types of database queries.

Support for the Use of a UDP in a USING Clause for SELECT and INSERT Statements

Version 3.3.0 enables the use of a UDP with a Using Clause to create SELECT and INSERT statements.

Graph LakeHouse Crashes While Running ES Index Query

Version 3.3.0 fixes an issue wherein AnzoGraph crashes while executing an Elasticsearch index query from Graph Studio owing to the creation of >100 GROUP_CONCAT(DISTINCT ...) aggregates.

Numeric Overflow When Calculating Date/Time Deltas for Values Far from the Epoch

Version 3.3.0 resolves a numeric overflow issue in GDI when calculating date/time deltas for values far from the epoch (e.g. 0215-03-18T00:00:00Z).

Invalid Results when Running a Query with Multiple Options/Clauses/Bindings

Version 3.3.0 resolves an in which queries containing multiple options, clauses, or bindings yield incorrect results.
