Connecting to Your Cluster

You can connect to your cluster by using the following clients:

Java Thin Client
.NET Thin Client
[.NET LINQ Thin Client]
[C++ Thin Client]

Connection URI and API credentials

All examples below contain the {connectionUri}, {login} and {password} values. You can get {connectionUri} from in Connections widget and {login} and {password} from My cluster tab.

Java Thin Client

Java thin client is a lightweight client that connects to the cluster via a standard socket connection. It does not become a part of the cluster topology, never holds any data, and is not used as a destination for compute calculations. The thin client simply establishes a socket connection to a standard node and performs all operations through that node.

Add the following dependencies to your Maven project:

<repositories>
    <repository>
        <id>GridGain External Repository</id>
        <url>https://www.gridgainsystems.com/nexus/content/repositories/external</url>
    </repository>
</repositories>

<dependencies>
    <dependency>
        <groupId>org.gridgain</groupId>
        <artifactId>ignite-core</artifactId>
        <version>${gg.version}</version>
    </dependency>
</dependencies>

Create a client configuration and replace the {login} and {password} placeholders with your cluster credentials.

    public static void main(String[] args) {
        SslConfiguration sslConfiguration = new SslConfigurationBuilder()
                .enabled(true)
                .build();
        IgniteClientAuthenticator auth = BasicAuthenticator.builder()
                .username("{login}")
                .password("{password}")
                .build();
// Connect to the cluster.
        try (IgniteClient client = IgniteClient.builder()
                .addresses("{connectionUri}:10800")
                .authenticator(auth)
                .ssl(sslConfiguration)
                .build()) {
// Query the table using SQL.
            client.sql().execute(null, "CREATE TABLE IF NOT EXISTS Person (id VARCHAR PRIMARY KEY, name VARCHAR)");

        }
    }

.NET Thin Client

Prerequisites:

Supported runtimes: .NET 8.0+
1. Install .NET SDK
2. Copy Program and dependency example files to an empty folder.
3. Replace the {gg.version} parameter that should match the version of the managed cluster.
4. Replace the {login} and {password} placeholders with your cluster API credentials.
5. Execute dotnet run in that folder.
