Requirements

This page outlines the requirements for using each ScalarDB component, including the programming languages and their versions, supported databases and their versions, and the necessary configurations.

Core​

ScalarDB Core is a key component of ScalarDB, providing a database manager with an abstraction layer that abstracts underlying databases. For more information, see ScalarDB Design.

Languages and runtimes​

ScalarDB Core provides a Java client SDK for interacting with ScalarDB. It also includes tools, such as Schema Loader and Data Loader, which run on the Java Virtual Machine (JVM).

Java​

The ScalarDB Core library is available on the Maven Central Repository. You can add the library as a build dependency to your application by using Gradle or Maven. For more details, see Add ScalarDB to Your Build.

For building applications that integrate with the library, the following Java Development Kits (JDKs) are verified and supported.

Java Runtime Environments (JREs) of these JDKs are also supported for running the tools.

Databases​

ScalarDB runs on top of the following databases and their versions.

Cluster​

ScalarDB Cluster is a component that provides a clustering solution for the Core component to work as a clustered server. For more information, see ScalarDB Design.

Languages and runtimes​

ScalarDB Cluster provides Java and .NET client SDKs that wrap gRPC-generated clients for ease of use.

Java​

The Java client SDK for ScalarDB Cluster is available on the Maven Central Repository. You can add the library as a build dependency to your application by using Gradle or Maven. For more details, see Add ScalarDB Cluster Java Client SDK to your build.

For building applications that integrate with the library, the following Java Development Kits (JDKs) are verified and supported:

.NET​

The .NET client SDK for ScalarDB Cluster is available as a NuGet package. For more details, see Install the SDK.

For building applications that integrate with the library, the following .NET versions are verified and supported:

Other languages​

Since ScalarDB Cluster uses gRPC, you can also create your own client in your preferred language by using the generated clients from the proto file. If you need the proto file, please contact support.

Databases​

Since ScalarDB Cluster uses Core to interact with databases, the requirements for databases are the same as those for Core. For more information, see Databases.

Required ports​

ScalarDB Cluster requires the following ports to be accessible. These default port numbers can be configured as needed:

  • 60053 (Administrative API / Transactional API / SQL API / pause operation)
  • 8080 (GraphQL)
  • 9080 (metrics)

Kubernetes​

ScalarDB Cluster is provided as a cluster consisting of one or more Pods on the Kubernetes platform in production environments. ScalarDB Cluster supports the following platforms and tools.
