Scalar Inc. Releases "ScalarDB 3.18," Enhancing Security and Governance for Distributed Data Infrastructures
Scalar Inc. has released ScalarDB 3.18, the latest version of its Universal HTAP engine "ScalarDB," which virtually integrates multiple, heterogeneous databases to handle both transaction and analytical processing. This version significantly enhances authentication and authorization functions for both ScalarDB Cluster (transaction base) and ScalarDB Analytics (analytical base), and now supports Google Cloud Spanner, enabling more unified and strict control over data access across multiple databases.

Scalar Inc. (Headquarters: Shinjuku-ku, Tokyo; Representative Director CEO: Wataru Fukatsu; Representative Director CTO: Hiroyuki Yamada) has released version 3.18, the latest edition of "ScalarDB," its Universal HTAP engine that virtually integrates multiple, heterogeneous databases to achieve both transaction and analytical processing.
This version focuses on strengthening the security and governance required for distributed data infrastructures, significantly expanding authentication and authorization functions for both ScalarDB Cluster, which serves as the transaction base, and ScalarDB Analytics, which serves as the analytical base. This enables enterprises to control data access across multiple databases in a more unified and strict manner. Additionally, with ScalarDB Core, which underpins ScalarDB Cluster, now supporting Google Cloud Spanner, transaction processing across multiple databases, including Spanner, has become possible.
In enterprise systems, it has become common for data to be distributed across multiple clouds and various types of databases. However, cross-sectional utilization of data while maintaining security policies, access rights, and auditability remains a difficult challenge. ScalarDB 3.18 is an update that further enhances its value as a secure and controllable distributed data utilization platform to address these challenges.
Background of the New Version Release
With the full-scale adoption of AI and the digitalization of operations, enterprise data infrastructures are shifting from a single-database-centric configuration to one based on multiple systems, multiple clouds, and multiple databases. In such environments, merely being able to utilize data across the board is insufficient; consistently managing who can access which data under what conditions is a critical management and operational requirement.
Especially in the enterprise domain, the integration of authentication and authorization, fine-grained access control, linkage with existing identity infrastructures, and the establishment of cross-cloud governance are indispensable. Furthermore, as system modernization and microservices adoption progress, there is a demand for flexibility to achieve consistent transaction and analytical processing without narrowing the choice of databases to be used.
ScalarDB 3.18 is a version that responds to these demands by strengthening security and governance and expanding supported databases.
Overview of New Features in ScalarDB 3.18
Supports token-based access control linked with enterprise IdP (Identity Provider) to strengthen security and governance of distributed data infrastructures.
ScalarDB Cluster, which handles transaction management, now supports access control using JWT access tokens issued by OIDC-compliant IdPs. Clients can access ScalarDB Cluster using access tokens obtained from an IdP, and ScalarDB Cluster verifies these tokens to perform access control based on the user's permissions corresponding to the client.
Furthermore, ABAC (Attribute-Based Access Control) tags can be specified in the JWT claims, allowing for fine-grained access control based on user attributes and business conditions. This enables unified and flexible access management for distributed data infrastructures spanning multiple databases, while linking with existing enterprise IdPs.
As a result, enterprises can strengthen governance without compromising the flexibility of data utilization, while balancing security policies and business requirements.
ScalarDB Analytics also supports authentication and authorization, improving overall control of the analytical infrastructure.
ScalarDB Analytics, which enables analytical queries across multiple databases, has also added new authentication and authorization functions. This allows access control for multiple underlying databases to be managed on ScalarDB Analytics.
Moreover, if the analytical target is a database under ScalarDB Cluster, authentication and authorization can be delegated to ScalarDB Cluster. This enables more consistent design and operation of access control spanning both transaction and analytical processing. Enterprises can more easily maintain data governance under a unified security policy while advancing analytical utilization.
Supports Google Cloud Spanner, expanding the flexibility of multi-database strategies.
