The Java SDK for YDB enables Java developers to work with Yandex Database.
Before you begin, you need to create a database and setup authorization. Please see the Prerequisites section of the connection guide in documentation for information on how to do that.
To use YDB Java SDK you will need Java 1.8+.
The recommended way to use the YDB Java SDK in your project is to consume it from Maven. Specify the SDK Maven modules that your project needs in the dependencies:
<dependencies>
<dependency>
<groupId>com.yandex.ydb</groupId>
<artifactId>ydb-sdk-core</artifactId>
<version>1.14.12</version>
</dependency>
<dependency>
<groupId>com.yandex.ydb</groupId>
<artifactId>ydb-sdk-table</artifactId>
<version>1.14.12</version>
</dependency>
<dependency>
<groupId>com.yandex.ydb</groupId>
<artifactId>ydb-sdk-auth-iam</artifactId>
<version>1.14.12</version>
</dependency>
