Scalar DB

CircleCI

A library that makes non-ACID distributed databases/storages ACID-compliant. It not only supports strongly-consistent ACID transactions, but also scales linearly and achieves high availability when it is deployed with distributed databases/storages such as Cassandra.

Install

The library is available on Maven Central. You can install it in your application using your build tool such as Gradle. For example in Gradle, you can add the following dependency to your build.gradle. Please replace the <version> with the version you want to use.

dependencies {
    compile group: 'com.scalar-labs', name: 'scalardb', version: '<version>'
}
