Use the CData Connector for Azure Table in APOS Live Data Gateway to build Semantic Layer Views for Azure Table data.
APOS Live Data Gateway (LDG) is a data connection and data transformation solution that enables live data connectivity and expanded data source options for SAP Analytics Cloud and other SAP solutions. When paired with CData Connectors, users can build semantic layer views for live Azure Table data, enabling real-time analytics on Azure Table just like working with a relational database.
With built-in optimized data processing, the CData Connector offers unmatched performance for interacting with live Azure Table data. When you issue complex SQL queries to Azure Table, the driver pushes supported SQL operations, like filters and aggregations, directly to Azure Table and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze Azure Table data using native data types.
Download and Install the Connector Files
In order to access Azure Table data through the APOS Live Data Gateway, you will need to download the connector files from APOS and install them on the machine hosting the Live Data Gateway. An APOS representative can deliver the necessary files.
- Install the CData DLL file (System.Data.CData.AzureTables.dll) to the APOS Live Data Gateway installation directory (C:\Program Files\Live Data Gateway\Admin\ by default).
- Install the CData JAR file (cdata.jdbc.azuretables.jar) to the ConnectionTest_lib folder in the installation directory (C:\Program Files\Live Data Gateway\Admin\ConnectionTest_lib\ by default).
- Install the CData JAR file (cdata.jdbc.azuretables.jar) to the lib folder in the Web UI installation directory (e.g.: C:\LDG_WebUI\lib\)
Configuring the Azure Table Connection String
Before establishing the connection to Azure Table from the APOS Live Data Gateway, you need to configure the Azure Table JDBC Connection String.
Built-in Connection String Designer
For assistance in constructing the JDBC Connection String, use the connection string designer built into the Azure Table JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.azuretables.jar
Fill in the connection properties and copy the connection string to the clipboard.
Specify your AccessKey and your Account to connect. Set the Account property to the Storage Account Name and set AccessKey to one of the Access Keys. Either the Primary or Secondary Access Keys can be used. To obtain these values, navigate to the Storage Accounts blade in the Azure portal. You can obtain the access key by selecting your account and clicking Access Keys in the Settings section.
Your connection string will look similar to the following:
jdbc:AzureTables:AccessKey=myAccessKey;Account=myAccountName;
Connecting to Azure Table & Creating a Semantic Layer View
After installing the connector files and configuring the connection string, you are ready to connect to Azure Table in the Live Data Gateway Admin tool and build a semantic layer view in the Live Data Gateway Web UI.
Configuring the Connection to Azure Table
- Log into your APOS Live Data Gateway Manager
- If you haven't already, update your APOS LDG license file
- Click File -> Configurations
- Click on the "..." Menu for the License
- Select the license file from the APOS team that includes your CData Connector license
- In the APOS Live Data Gateway Manager, click "Add"
- In the APOS Live Data Gateway On the Connection tab, configure the connection:
- Set Data Source to "Database"
- Set Database to "CData Drivers"
- Set Database CData Drivers to "Azure Table"
- Set Connection String to the connection string configured earlier (e.g.:
jdbc:AzureTables:AccessKey=myAccessKey;Account=myAccountName;
- Set Driver Class to "cdata.jdbc.azuretables.AzureTablesDriver" (this should be set by default)
- Click Test Connection
- Click Save
- Give your connection a unique prefix (e.g. "azuretables")
- Highlight the newly created connection and click File -> "Approve Users For Web UI"
- Approve the appropriate DB users to create views and click "Save"
At this point, we are ready to build our semantic layer view in the Live Data Gateway Web UI.
Creating a Semantic Layer View
- In your browser, navigate to the APOS Live Data Gateway Portal
- Select a Connection (e.g. "azuretables")
- Since Azure Table does not require a User or Password to authenticate, you may use whatever values you wish for User Name and Password
- Click "Login"
- Once connected, click "Semantic Layer" to create a new semantic layer view
- Click "New Semantic Layer View"
- Set the Semantic Layer View Prefix and Semantic Layer View Name
- Click "Step 2"
- Select the table(s) and column(s) you wish to include in your view
- Click "Step 3"
- Select the Measures from the available table columns
- Click "Step 5" (we skipped the "Extra Dimensions" step)
- Add any Variable Prompts
- Click "Step 6"
- Define any Table Joins
- Click "Review"
- Review you semantic layer view and click "Save"
With the Semantic Layer View created, you are ready to access your Azure Table data through the APOS Live Data Gateway, enabling real-time data connectivity to Azure Table data from SAP Analytics Cloud and other SAP solutions.
