How to integrate Starburst using Java

Learn how to quickly and efficiently connect Starburst with Java for smooth data access.

Read and write Starburst (Trino) data effortlessly. Query, analyze, and integrate catalogs and data from multiple sources — almost no coding required. You can do it all using the high-performance Starburst ODBC Driver for Java (often referred to as the Starburst Connector). How is this possible? You will connect to the ZappySys Data Gateway, which acts as a seamless bridge between the ODBC and JDBC layers. We'll walk you through the entire setup.

Starburst ODBC Driver Powering this integration

High performance
Bidirectional
Low-code / No-code
Easy to use

Built on the ZappySys JDBC Bridge Driver, the Starburst ODBC Driver is a high-performance, low-code / no-code solution. It enables you to connect to Starburst data without any coding right in your SQL Server, or any ODBC/JDBC application. Part of the ODBC PowerPack.

Documentation

Prerequisites

Before we begin, make sure you meet the following prerequisite: Java Runtime Environment (JRE) or Java Development Kit (JDK) must be installed on your system.

Minimum required version: Java 11
- Amazon Corretto 11
- Oracle JRE 11
Recommended Java version: Java 21
- Amazon Corretto 21
- Oracle JRE 21

If your JDBC Driver targets a different Java version (e.g., 11 / 17 / 21), install the corresponding or newer Java version.

If you already have a JRE installed, you can try using it too. However, if you experience any issues, we recommend using one of the distributions mentioned above (you can install an additional JRE next to the existing one; just don't forget to configure the default Java in the Windows Environment Variables).

Download Starburst JDBC driver

To connect to Starburst in , you will have to download JDBC driver for it, which we will use in later steps. Let's perform these little steps right away:

Visit Starburst official website.
Download the JDBC driver, and save it locally, e.g. to D:\Drivers\JDBC\trino-jdbc.jar.
Done! That was easy, wasn't it? Let's proceed to the next step.

Create data source in ZappySys Data Gateway

In this section we will create a data source for Starburst in the Data Gateway. Let's follow these steps to accomplish that:

Download and install ODBC PowerPack (if you haven't already).
Search for gateway in the Windows Start Menu and open ZappySys Data Gateway Configuration:
Go to the Users tab and follow these steps to add a Data Gateway user:
- Click the Add button
- In the Login field enter a username, e.g., john
- Then enter a Password
- Check the Is Administrator checkbox
- Click OK to save
Now we are ready to add a data source:
- Click the Add button
- Give the Data source a name (have it handy for later)
- Then select Native - ZappySys JDBC Bridge Driver
- Finally, click OK
StarburstDSN

ZappySys JDBC Bridge Driver
Now, we need to configure the JDBC connection in the new ODBC data source. Simply enter the Connection string, credentials, configure other settings, and then click Test Connection button to test the connection:

StarburstDSN

jdbc:trino://trino-instance-host-name:8080

D:\Drivers\JDBC\trino-jdbc.jar

admin

****************

[]

Use these values when setting parameters:
- Connection string: jdbc:trino://trino-instance-host-name:8080
- JDBC driver file(s): D:\Drivers\JDBC\trino-jdbc.jar
- User name: admin
- User password: ****************
- Connection parameters: []
You should see a message saying that connection test is successful:

Otherwise, if you are getting an error, check out our Community for troubleshooting tips.
We are at the point where we can preview a SQL query. For more SQL query examples visit JDBC Bridge documentation:
StarburstDSN
```
SELECT * FROM tpch.sf1.orders
```
```
SELECT * FROM tpch.sf1.orders
```
You can also click on the <Select Table> dropdown and select a table from the list.

The ZappySys JDBC Bridge Driver acts as a transparent intermediary, passing SQL queries directly to the JDBC driver, which then handles the query execution. This means the Bridge Driver simply relays the SQL query without altering it.

Some JDBC drivers don't support INSERT/UPDATE/DELETE statements, so you may get an error saying "action is not supported" or a similar one. Please, be aware, this is not the limitation of ZappySys JDBC Bridge Driver, but is a limitation of the specific JDBC driver you are using.
Click OK to finish creating the data source.
Once done, go to the Network Settings tab and Add a firewall rule for inbound traffic:
- This will initially allow all inbound traffic.
- Click Edit IP filters to restrict access to specific IP addresses or ranges.
Crucial Step: After creating or modifying the data source, you must:
- Click the Save button to persist your changes.
- Hit Yes when prompted to restart the Data Gateway service.
This ensures all changes are properly applied:

Skipping this step may cause the new settings to fail, preventing you from connecting to the data source.

Read data in Java from the DSN

Java code to get the data:

"jdbc:sqlserver://localhost:5000;databasename=StarburstDSN;user=john;password=test"
When you run the code it will make the API call and read the data:

Here is Java program's code in text format:

        // Create a variable for the connection string.
        String connectionUrl = "jdbc:sqlserver://localhost:5000;databasename=StarburstDSN;user=test;password=test";

        // Declare the JDBC objects.
        Connection con = null;
        Statement stmt = null;
        ResultSet rs = null;

            try {

                Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
                con = DriverManager.getConnection(connectionUrl);

                // Create and execute an SQL statement that returns some data.
                String SQL = "SELECT Country , SUM(UnitPrice * Quantity) Total " 
                           + "FROM value " 
                           + "GROUP BY Country "
                           + "WITH (SRC='https://services.odata.org/V3/Northwind/Northwind.svc/Invoices?$format=json')";
                stmt = con.createStatement();
                rs = stmt.executeQuery(SQL);

                // Iterate through the data in the result set and display it.
                while (rs.next()) {
                    System.out.println(rs.getString(1) + " " + rs.getString(2));
                }
            }

        // Handle any errors that may have occurred.
        catch (Exception e) {
            e.printStackTrace();
        } 
        
        finally {
            if (rs != null) try { rs.close(); } catch (Exception e) {}
            if (stmt != null) try { stmt.close(); } catch (Exception e) {}
            if (con != null) try { con.close(); } catch (Exception e) {}
        }
    }
}
