Automated Continuous Presto Replication to MongoDB

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

Configure MongoDB as a Replication Destination

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

1. Click Add Connection.
2. Select MongoDB as a destination.
3. Enter the necessary connection properties. To connect to MongoDB, set the following:
   • Server: Set this to the name or address of the server where your MongoDB instance is running. You can specify the port here or in Port.
   • Database: Set this to the database you want to read from and write to.

   Connecting to CosmosDB with the MongoDB API

   To obtain the connection string needed to connect to a Cosmos DB account using the MongoDB API, log in to the Azure Portal, select Azure Cosmos DB, and select your account. In the Settings section, click Connection String and set the following values.

   • Server: Set this to the Host value, the FQDN of the server provisioned for your account. You can also specify the port here or in Port.
   • Port: Set this to the port.
   • Database: Set this to the database you want to read from and write to.
   • User: Set this to the database user.
   • Password: Set this to the user's password.

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

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.

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 MongoDB.
