Build Presto-Connected Visualizations in datapine
Use CData Connect Cloud and datapine to build visualizations and dashboards with access to live Presto data.
datapine is a browser-based business intelligence platform. When paired with the CData Connect Cloud, you get access to your Presto data directly from your datapine visualizations and dashboards. This article describes connecting to Presto in CData Connect Cloud and building a simple Presto-connected visualization in datapine.
CData Connect Cloud provides a pure SQL Server interface for Presto, allowing you to query data from Presto without replicating the data to a natively supported database. Using optimized data processing out of the box, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc.) directly to Presto, leveraging server-side processing to return the requested Presto data quickly.
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 Presto Connectivity for datapine
Connectivity to Presto from datapine is made possible through CData Connect Cloud. To work with Presto data from datapine, we start by creating and configuring a Presto connection.
- Log into Connect Cloud, click Sources, and then click Add Connection
- Select "Presto" from the Add Connection panel
-
Enter the necessary authentication properties to connect to Presto.
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 Create & Test
-
Navigate to the Permissions tab in the Add Presto Connection page and update the User-based permissions.
Add a Personal Access Token
When connecting to Connect Cloud through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect Cloud. It is best practice to create a separate PAT for each service to maintain granularity of access.
- Click on the Gear icon () at the top right of the Connect Cloud app to open the settings page.
- On the Settings page, go to the Access Tokens section and click Create PAT.
-
Give the PAT a name and click Create.
- The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.
With the connection configured and a PAT generated, you are ready to connect to Presto data from datapine.
Connecting to Presto from datapine
Once you configure your connection to Presto in Connect Cloud, you are ready to connect to Presto from datapine.
- Log into datapine
- Click Connect to navigate to the "Connect" page
- Select MS SQL Server as the data source
- In the Integration step, fill in the connection properties and click "Save and Proceed"
- Set the Internal Name
- Set Database Name to the name of the connection we just configured (e.g. Presto1)
- Set Host / IP to "tds.cdata.com"
- Set Username to your Connect Cloud username (e.g. [email protected])
- Set Password to the corresponding PAT
- Set Database Port to "14333"
- In the Data Schema step, select the tables and fields to visualize and click "Save and Proceed"
- In the References step, define any relationships between your selected tables and click "Save and Proceed"
- In the Data Transfer step, click "Go to Analyzer"
