Analyze Impala Data in SAP Analytics Cloud

SAP Analytics Cloud is a cloud-based business intelligence platform. CData Connect AI creates a pure, cloud-to-cloud connection to Impala and can be used to generate an OData API (natively supported in Analytics Cloud) for Impala. By pairing SAP Analytics Cloud with CData Connect AI, you get true cloud-to-cloud connectivity to all of your SaaS and cloud-based Big Data and NoSQL sources — no need to migrate your data or write your integrations. Simply connect to Connect AI as you would any other OData service and get instant, consolidated access to all of your data.

In this article, we walk through connecting to Impala from SAP Analytics Cloud (through CData Connect AI) to create a model and build a simple dashboard.

Connect to Impala from SAP Analytics Cloud

To work with live Impala data in SAP Analytics Cloud, we need to connect to Impala from Connect AI, provide user access to the connection, and create a Workspace for the Impala data.

Connect to Impala from Connect AI

CData Connect AI uses a straightforward, point-and-click interface to connect to data sources.

1. Log into Connect AI, click Sources, and then click Add Connection
👁 Adding a Connection

2. Select "Impala" from the Add Connection panel
👁 Selecting a data source

3. Enter the necessary authentication properties to connect to Impala.

   In order to connect to Apache Impala, set the Server, Port, and ProtocolVersion. You may optionally specify a default Database. To connect using alternative methods, such as NOSASL, LDAP, or Kerberos, refer to the online Help documentation.

4. Click Save & Test
5. Navigate to the Permissions tab in the Add Impala Connection page and update the User-based permissions. 👁 Updating permissions
   

Add a Personal Access Token

When connecting to Connect AI 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 AI. It is best practice to create a separate PAT for each service to maintain granularity of access.

1. Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
2. On the Settings page, go to the Access Tokens section and click Create PAT.
3. Give the PAT a name and click Create. 👁 Creating a new PAT
   
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

Configure Impala Endpoints for SAP Analytics Cloud

After connecting to Impala, create a workspace for your desired table(s).

1. Navigate to the Workspaces page and click Add to create a new Workspace (or select an existing workspace). 👁 The Workspaces page.
   👁 Adding a new Workspace.
   
2. Click Add to add new assets to the Workspace.
3. Select the Impala connection (e.g. ApacheImpala1) and click Next. 👁 Selecting an Asset (Salesforce is shown).
   
4. Select the table(s) you wish to work with and click Confirm. 👁 Selecting Tables (Salesforce is shown).
   
5. 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 Impala data from SAP Analytics Cloud.

Create a Model of Impala Data in SAP Analytics Cloud

With the connection to Impala configured and the OData endpoint(s) created, we can create a Model for Impala data in SAP Analytics Cloud.

1. Log into your Analytics Cloud instance and click Create -> Model from the menu.
2. Choose "Get data from a datasource" and select "OData Services"
3. Choose an existing connection to your Connect AI OData or Create a new one:
   • Set Connection Name
   • Set Data Service URL to the Base URL for your OData API: https://cloud.cdata.com/api/odata/{workspace_name}
   • Set Authentication Type to Basic Authentication
   • Set User Name to the Connect AI user (e.g. [email protected])
   • Set Password to the PAT for the above user
   👁 Creating a new OData Services Connection
   
4. Choose "Create a new query" and click Next
5. Name the Execute, select an OData endpoint (like Customers) and click Next 👁 Choosing a Connect AI OData endpoint to query
   
6. Drag the columns you wish to work with into the Selected Data workspace and click Create 👁 Selecting fields (columns) from the OData endpoint
   
7. At this point, a Draft Data source is created; click the draft to finalize the model
8. Perform any transformations, including creating calculated dimensions, location dimensions, and combining data sources, then click Create Model 👁 Finalizing the model
   
9. Name your model and click OK

Build a Dashboard in SAP Analytics Cloud

With the model created, you are ready to create a dashboard in SAP Analytics Cloud based on Impala data.

1. From the menu, click Create -> Story
2. Click on SAP Analytics Template (this article uses the "Dashboard" template)
3. Choose a layout and click Apply
4. From the More menu, select a visualization to insert (Chart) 👁 Inserting a visualization
   
5. Select a model to visualize
6. Select a structure and the required Measures and Dimensions
7. Save the store 👁 Saving the Story
