Use CData Connect Cloud to Access Presto Data in Microsoft Power Pivot
Use CData Connect Cloud to connect to live Presto data in the Power Pivot business intelligence tool.
This article will explain how to use CData Connect Cloud to present Presto data as OData services and then consume the data in Microsoft Excel's Power Pivot business intelligence tool. Follow the steps below to retrieve and edit Presto data in Power Pivot.
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
Connect to Presto from Power Pivot
To work with Presto data from Power Pivot, we need to connect to Presto from Connect Cloud, provide user access to the connection, and create a Workspace for the Presto data.
Connect to Presto from Connect Cloud
CData Connect Cloud uses a straightforward, point-and-click interface to connect to data sources.
- 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.
Configure Presto Endpoints for Power Pivot
After connecting to Presto, create a workspace for your desired table(s).
-
Navigate to the Workspaces page and click Add to create a new Workspace (or select an existing workspace).
- Click Add to add new assets to the Workspace.
-
Select the Presto connection (e.g. Presto1) and click Next.
-
Select the table(s) you wish to work with and click Confirm.
- Make note of the OData Service URL for your workspace, e.g. https://cloud.cdata.com/api/odata/{workspace_name}
With the connection, PAT, and Workspace configured, you are ready to connect to Presto data from Power Pivot.
Import Presto Tables in Power Pivot
Follow the steps below to import tables that can be refreshed on demand:
-
In Excel, click Data -> Get Data -> From Other Sources -> From OData Feed
-
Fill out the OData feed URL (e.g. https://cloud.cdata.com/api/odata/{workspace_name})
-
On the next screen, select Basic and configure the username and password. Password will be your PAT.
-
Select the tables that you would like to import into Excel
-
After selecting your table(s) and clicking Load, you should see the data appear in an Excel spreadsheet
-
Now, click the Power Pivot tab on the ribbon, and then select Add to Data Model.
This can now work with your Presto data in Power Pivot.
