Automated Continuous Presto Replication to Amazon S3
Use CData Sync for automated, continuous, customizable Presto replication to Amazon S3.
Always-on applications rely on automatic failover capabilities and real-time data access. CData Sync integrates live Presto data into your Amazon S3 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 Amazon S3 as a Replication Destination
Using CData Sync, you can replicate Presto data to Amazon S3. To add a replication destination, navigate to the Connections tab.
- Click Add Connection.
- Select Amazon S3 as a destination.
Enter the necessary connection properties. To connect to Amazon S3, provide the credentials for an administrator account or for an IAM user with custom permissions: Set AccessKey to the access key ID. Set SecretKey to the secret access key.
Note: Though you can connect as the AWS account administrator, it is recommended to use IAM user credentials to access AWS services.
To obtain the credentials for an IAM user, follow the steps below:
- Sign into the IAM console.
- In the navigation pane, select Users.
- To create or manage the access keys for a user, select the user and then select the Security Credentials tab.
To obtain the credentials for your AWS root account, follow the steps below:
- Sign into the AWS Management console with the credentials for your root account.
- Select your account name or number and select My Security Credentials in the menu that is displayed.
- Click Continue to Security Credentials and expand the Access Keys section to manage or create root account access keys.
- Click Test Connection to ensure that the connection is configured properly.
- 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.
- Click Add Connection.
- Select a source (Presto).
- 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.
- Click Connect to ensure that the connection is configured properly.
- 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 Amazon S3.
