Java driver

The Java driver was developed by Vaticle to enable TypeDB support for Java software and developers.

GitHub

The GitHub repository with the driver’s source code and release notes.

Maven

Install

See the Version Compatibility table to check what versions of TypeDB and Java driver are compatible.

For Linux: the minimum version of glibc is 2.25.0.

Add the code below to the pom.xml file in the Maven project.

Replace the {version} placeholder tag with the version of the Java driver you want to install.

 
<repositories>
    <repository>
        <id>repo.typedb.com</id>
        <url>https://repo.typedb.com/public/public-release/maven/</url>

<dependencies>
    <dependency>
        <groupId>com.vaticle.typedb</groupId>
        <artifactId>typedb-driver</artifactId>
        <version>{version}</version>
    </dependency>
</dependencies>

For more information, see the build systems setup page.

To use the TypeQL library, see the Java query builder page for installation instructions.

Add logging config

By default, the Java driver uses Logback to print errors and debugging info to standard output. As it is quite verbose, you can use the following steps to set the minimum log level to ERROR:

  1. Create a file in the resources path (src/main/resources by default in a Maven project) named logback.xml.

  2. Copy the following document into the logback.xml:

<configuration>
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>
    <root level="ERROR">
        <appender-ref ref="STDOUT"/>
    </root>
</configuration>

Quickstart

See below a short example of Java code that connects to a local TypeDB Core, creates a database named access-management-db, defines a schema, inserts some data, and then reads it.

package org.example;
import com.vaticle.typedb.driver.TypeDB;
import com.vaticle.typedb.driver.api.TypeDBDriver;
import com.vaticle.typedb.driver.api.TypeDBSession;
import com.vaticle.typedb.driver.api.TypeDBTransaction;
import com.vaticle.typeql.lang.TypeQL;
import com.vaticle.typeql.lang.common.TypeQLArg;
import com.vaticle.typeql.lang.common.TypeQLToken;
import com.vaticle.typeql.lang.query.TypeQLDefine;
import com.vaticle.typeql.lang.query.TypeQLInsert;
import com.vaticle.typeql.lang.query.TypeQLFetch;

public class Main {

    public static void main(String[] args) {
        final String DB_NAME = "access-management-db";
        final String SERVER_ADDR = "127.0.0.1:1729";

        try (TypeDBDriver driver = TypeDB.coreDriver(SERVER_ADDR)) {

            if (driver.databases().contains(DB_NAME)) {
                driver.databases().get(DB_NAME).delete();
            }
            driver.databases().create(DB_NAME);

            try (TypeDBSession session = driver.session(DB_NAME, TypeDBSession.Type.SCHEMA)) {
                try (TypeDBTransaction tx = session.transaction(TypeDBTransaction.Type.WRITE)) {
                    TypeQLDefine defineQuery = TypeQL.define(
                                    TypeQL.type("person").sub(TypeQLToken.Type.ENTITY).owns("name"),
                                    TypeQL.type("name").sub(TypeQLToken.Type.ATTRIBUTE).value(TypeQLArg.ValueType.STRING)
                    );
                    tx.query().define(defineQuery);
                    tx.commit();
                }
            }
            try (TypeDBSession session = driver.session(DB_NAME, TypeDBSession.Type.DATA)) {
                try (TypeDBTransaction tx = session.transaction(TypeDBTransaction.Type.WRITE)) {
                    TypeQLInsert insertQuery = TypeQL.insert(
                            TypeQL.cVar("p1").isa("person").has("name", "Alice"),
                            TypeQL.cVar("p2").isa("person").has("name","Bob")
                    );
                    tx.query().insert(insertQuery);
                    tx.commit();
                    }
                try (TypeDBTransaction tx = session.transaction(TypeDBTransaction.Type.READ)) {
                    TypeQLFetch fetchQuery = TypeQL.match(
                            TypeQL.cVar("p").isa("person")
                    ).fetch(TypeQL.cVar("p").map("name"));
                    tx.query().fetch(fetchQuery).forEach(result -> System.out.println(result.toString()));
                }
            }
        }
    }
}

The above example uses Java query builder syntax to construct TypeQL queries. For more code examples, see the Tutorial and API reference links below.
