Automated Continuous Presto Replication to Amazon Redshift

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

Configure Amazon Redshift as a Replication Destination

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

1. Click Add Connection.
2. Select Amazon Redshift as a destination.
3. Enter the necessary connection properties. To connect to Amazon Redshift, set the following:
   • Server: Set this to the host name or IP address of the cluster hosting the Database you want to connect to.
   • Port: Set this to the port of the cluster.
   • Database: Set this to the name of the database. Or, leave this blank to use the default database of the authenticated user.
   • User: Set this to the username you want to use to authenticate to the Server.
   • Password: Set this to the password you want to use to authenticate to the Server.

   You can obtain these values in the AWS Management Console:

   1. Open the Amazon Redshift console.
   2. On the Clusters page, click the name of the cluster.
   3. On the Configuration tab, obtain the properties from the Cluster Database Properties section. The connection property values will be the same as the values set in the ODBC URL.

4. Click Test Connection to ensure that the connection is configured properly.
5. Click Save Changes.

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 ensure that the connection is configured properly.

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, click Add Tables in the Tables section, choose the table(s) you wish to replicate, and click Add Selected Tables.

Customize Your Replication

Schedule Your Replication

In the Schedule section, you can schedule a job to run automatically, configuring the job to run after 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 Amazon Redshift.
