Connect to SingleStore Data in HULFT Integrate

HULFT Integrate is a modern data integration platform that provides a drag-and-drop user interface to create cooperation flows, data conversion, and processing so that complex data connections are easier than ever to execute. When paired with the CData JDBC Driver for SingleStore, HULFT Integrate can work with live SingleStore data. This article walks through connecting to SingleStore and moving the data into a CSV file.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live SingleStore data. When you issue complex SQL queries to SingleStore, the driver pushes supported SQL operations, like filters and aggregations, directly to SingleStore and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze SingleStore data using native data types.

Enable Access to SingleStore

To enable access to SingleStore data from HULFT Integrate projects:

1. Copy the CData JDBC Driver JAR file (and license file if it exists), cdata.jdbc.singlestore.jar (and cdata.jdbc.singlestore.lic), to the jdbc_adapter subfolder for the Integrate Server
2. Restart the HULFT Integrate Server and launch HULFT Integrate Studio

Build a Project with Access to SingleStore Data

Once you copy the JAR files, you can create a project with access to SingleStore data. Start by opening Integrate Studio and creating a new project.

1. Name the project
2. Ensure the "Create script" checkbox is checked
3. Click Next
4. Name the script (e.g.: SingleStoretoCSV)

Once you create the project, add components to the script to copy SingleStore data to a CSV file.

Configure an Execute Select SQL Component

Drag an "Execute Select SQL" component from the Tool Palette (Database -> JDBC) into the Script workspace.

1. In the "Required settings" tab for the Destination, click "Add" to create a new connection for SingleStore. Set the following properties:
   • Name: SingleStore Connection Settings
   • Driver class name: cdata.jdbc.singlestore.SingleStoreDriver
   • URL: jdbc:singlestore:User=myUser;Password=myPassword;Database=NorthWind;Server=myServer;Port=3306;
     
     

     Built-in Connection String Designer

     For assistance constructing the JDBC URL, use the connection string designer built into the SingleStore JDBC Driver. Either double-click the JAR file or execute the JAR file from the command-line.

     java -jar cdata.jdbc.singlestore.jar

     Fill in the connection properties and copy the connection string to the clipboard.

     The following connection properties are required in order to connect to data.

     • Server: The host name or IP of the server hosting the SingleStore database.
     • Port: The port of the server hosting the SingleStore database.
     • Database (Optional): The default database to connect to when connecting to the SingleStore Server. If this is not set, tables from all databases will be returned.

     Connect Using Standard Authentication

     To authenticate using standard authentication, set the following:

     • User: The user which will be used to authenticate with the SingleStore server.
     • Password: The password which will be used to authenticate with the SingleStore server.

     Connect Using Integrated Security

     As an alternative to providing the standard username and password, you can set IntegratedSecurity to True to authenticate trusted users to the server via Windows Authentication.

     Connect Using SSL Authentication

     You can leverage SSL authentication to connect to SingleStore data via a secure session. Configure the following connection properties to connect to data:

     • SSLClientCert: Set this to the name of the certificate store for the client certificate. Used in the case of 2-way SSL, where truststore and keystore are kept on both the client and server machines.
     • SSLClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
     • SSLClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
     • SSLClientCertType: The certificate type of the client store.
     • SSLServerCert: The certificate to be accepted from the server.

     Connect Using SSH Authentication

     Using SSH, you can securely login to a remote machine. To access SingleStore data via SSH, configure the following connection properties:

     • SSHClientCert: Set this to the name of the certificate store for the client certificate.
     • SSHClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
     • SSHClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
     • SSHClientCertType: The certificate type of the client store.
     • SSHPassword: The password that you use to authenticate with the SSH server.
     • SSHPort: The port used for SSH operations.
     • SSHServer: The SSH authentication server you are trying to authenticate against.
     • SSHServerFingerPrint: The SSH Server fingerprint used for verification of the host you are connecting to.
     • SSHUser: Set this to the username that you use to authenticate with the SSH server.
2. Write your SQL statement. For example:

   SELECT ShipName, ShipCity FROM Orders

3. Click "Extraction test" to ensure the connection and query are configured properly
4. Click "Execute SQL statement and set output schema"
5. Click "Finish"

Configure a Write CSV File Component

Drag a "Write CSV File" component from the Tool Palette (File -> CSV) onto the workspace.

1. Set a file to write the query results to (e.g. Orders.csv)
2. Set "Input data" to the "Select SQL" component
3. Add columns for each field selected in the SQL query
4. In the "Write settings" tab, check the checkbox to "Insert column names into first row"
5. Click "Finish"

Map SingleStore Fields to the CSV Columns

Map each column from the "Select" component to the corresponding column for the "CSV" component.

Finish the Script

Drag the "Start" component onto the "Select" component and the "CSV" component onto the "End" component. Build the script and run the script to move SingleStore data into a CSV file.
