Use CData Sync for automated, continuous, customizable Presto replication to Azure SQL Database.

Always-on applications rely on automatic failover capabilities and real-time data access. CData Sync integrates live Presto data into your Azure SQL Database instance, allowing you to consolidate all of your data into a single location for archiving, reporting, analytics, machine learning, artificial intelligence and more.

About Presto Data Integration

Accessing and integrating live data from Trino and Presto SQL engines has never been easier with CData. Customers rely on CData connectivity to:

  • Access data from Trino v345 and above (formerly PrestoSQL) and Presto v0.242 and above (formerly PrestoDB)
  • Read and write access all of the data underlying your Trino or Presto instances
  • Optimized query generation for maximum throughput.

Presto and Trino allow users to access a variety of underlying data sources through a single endpoint. When paired with CData connectivity, users get pure, SQL-92 access to their instances, allowing them to integrate business data with a data warehouse or easily access live data directly from their preferred tools, like Power BI and Tableau.

In many cases, CData's live connectivity surpasses the native import functionality available in tools. One customer was unable to effectively use Power BI due to the size of the datasets needed for reporting. When the company implemented the CData Power BI Connector for Presto they were able to generate reports in real-time using the DirectQuery connection mode.


Getting Started


Configure Azure SQL Database as a Replication Destination

Using CData Sync, you can replicate Presto data to Azure SQL Database. To add a replication destination, navigate to the Connections tab.

  1. Click Add Connection. 👁 Add a new connection.
  2. Select the Destinations tab and locate the Azure SQL Database connector. 👁 Configure a Destination connection to Azure SQL Database.
  3. Click the Configure Connection icon at the end of that row to open the New Connection page. If the Configure Connection icon is not available, click the Download Connector icon to install the Azure SQL Database connector. For more information about installing new connectors, see Connections in the Help documentation.
  4. To connect to Azure SQL database, set the following connection properties:
    • Connection Name: Enter a connection name of your choice for the Azure SQL database connection.
    • Server: Enter the host name or IP of the server that hosts the Azure SQL database.
    • Port: Enter the port number of the server that hosts the Azure SQL database. The default port value is 1433
    • Database: Enter the name of the database.
    • Auth Scheme: Select the authentication scheme. The default auth scheme is SqlPassword.
    • User: Enter the user ID provided for authentication with the Azure SQL database.
    • Password: Enter the password provided for authentication with the Azure SQL database.
    5. 👁 Enter the connection details.
  5. Once connected, click Create & Test to create, test and save the connection.

You are now connected to Azure SQL database and can use it as both a source and a destination.

NOTE: You can use the Label feature to add a label for a source or a destination.

👁 Add a label.

In this article, we will demonstrate how to load Presto data into Azure SQL database and utilize it as a destination.

Configure the Presto Connection

You can configure a connection to Presto from the Connections tab. To add a connection to your Presto account, navigate to the Connections tab.

  1. Click Add Connection.
  2. Select a source (Presto).
  3. Configure the connection properties.

    Set the Server and Port connection properties to connect, in addition to any authentication properties that may be required.

    To enable TLS/SSL, set UseSSL to true.

    Authenticating with LDAP

    In order to authenticate with LDAP, set the following connection properties:

    • AuthScheme: Set this to LDAP.
    • User: The username being authenticated with in LDAP.
    • Password: The password associated with the User you are authenticating against LDAP with.

    Authenticating with Kerberos

    In order to authenticate with KERBEROS, set the following connection properties:

    • AuthScheme: Set this to KERBEROS.
    • KerberosKDC: The Kerberos Key Distribution Center (KDC) service used to authenticate the user.
    • KerberosRealm: The Kerberos Realm used to authenticate the user with.
    • KerberosSPN: The Service Principal Name for the Kerberos Domain Controller.
    • KerberosKeytabFile: The Keytab file containing your pairs of Kerberos principals and encrypted keys.
    • User: The user who is authenticating to Kerberos.
    • Password: The password used to authenticate to Kerberos.
    👁 Configuring a Source connection (Salesforce is shown).
  4. Click Connect to Presto to ensure that the connection is configured properly.
  5. Click Save & Test to save the changes.

Configure Replication Queries

CData Sync enables you to control replication with a point-and-click interface and with SQL queries. For each replication you wish to configure, navigate to the Jobs tab and click Add Job. Select the Source and Destination for your replication.

👁 Select Source and Destination connections for the replication.

Replicate Entire Tables

To replicate an entire table, navigate to the Task tab in the Job, click Add Tasks, choose the table(s) from the list of Presto tables you wish to replicate into Azure SQL database, and click Add Tasks again.

👁 Choose entire tables to replicate (Salesforce is shown).

Customize Your Replication

You can use the Columns and Query tabs of a task to customize your replication. The Columns tab allows you to specify which columns to replicate, rename the columns at the destination, and even perform operations on the source data before replicating. The Query tab allows you to add filters, grouping, and sorting to the replication with the help of SQL queries. 👁 Configure a replication Transform.

Schedule Your Replication

Select the Overview tab in the Job, and click Configure under Schedule. You can schedule a job to run automatically by configuring it to run at specified intervals, ranging from once every 10 minutes to once every month.

👁 Schedule your job to run automatically.

Once you have configured the replication job, click Save Changes. You can configure any number of jobs to manage the replication of your Presto data to Azure SQL database.

Run the Replication Job

Once all the required configurations are made for the job, select the Presto table you wish to replicate and click Run. After the replication completes successfully, a notification appears, showing the time taken to run the job and the number of rows replicated.

👁 Run the job.
