Replicate Multiple Presto Accounts

CData Sync is a standalone application designed to support a variety of replication scenarios, such as replicating both sandbox and production instances into your database. It includes a web-based interface that simplifies the management of multiple Presto connections. In this article, we demonstrate how to use the web app to replicate multiple Presto accounts into a single database.

Getting Started

---

Configure Replication Destinations

Using CData Sync, you can replicate data from Presto to any number of databases, both cloud-based and on-premises. In this example, we use SQLite as the replication destination to demonstrate the process. To add it as a destination, navigate to the Connections tab.

For each destination database:

1. Click Add Connection.
2. Select the Destinations tab and locate the SQLite connector.
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 SQLite connector. For more information about installing new connectors, see Connections in the Help documentation.
4. To connect to SQLite, set the following connection properties:
   • Connection Name: Enter a connection name of your choice.
   • Data Source: Enter the path to the database. You can replicate to an existing database or to a new one. The application must have permission to access the database.

5. Once connected, click Create & Test to create, test and save the connection.

You are now connected to SQLite 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.

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.
   
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.

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 SQLite, and click Add Tasks again.

Customize Your Replication

The statement below caches and incrementally updates a table of Presto data:

REPLICATE Customer;

You can specify a file containing the replication queries you want to use to update a particular database. Separate the replication statements with semicolons. The following options are useful when replicating multiple Presto accounts into the same database:

• Use a different table prefix in the REPLICATE SELECT statement:

  REPLICATE PROD_Customer SELECT * FROM Customer;
  

• Alternatively, use a different schema:

  REPLICATE PROD.Customer SELECT * FROM Customer;
  

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.

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 disparate on-premises, cloud-based, and other databases.

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.
