Impala BizTalk Adapter

Powerful BizTalk Adapters that allow you to easily connect BizTalk Server with live Impala data through standard orchestrations.

Use the Impala Adapters to synchronize with Impala data, etc. Perfect for data synchronization, local back-ups, workflow automation, and more!



You can use stored procedures provided by the CData BizTalk Adapter for Impala to automate working with Impala data in BizTalk. Stored procedures implement actions available in the underlying API.

Stored procedures implement Impala actions that cannot be represented as SELECT, INSERT, UPDATE, and DELETE statements. This article shows how to generate a schema for a stored procedure. You can use the schema to execute the stored procedure from a send port.

Add the Adapter to Your Project

Use the Add Adapter wizard to add the adapter to a BizTalk Server project in Visual Studio. The adapter will return metadata about the inputs of the stored procedure and its results. This metadata is needed to create the schema.

  1. Right-click on the project in the Solution Explorer and click Add -> Add Generated Items.
  2. Select Add Adapter Metadata in the resulting dialog box.
  3. In the resulting Add Adapter wizard, select the adapter from the list.
  4. In the Port menu, leave the selection blank. Or, select a receive location or send port that has been configured to use the Impala Adapter.
  5. On the Connection String page, enter authentication credentials and other connection properties if they were not already configured in the send port or the receive location.

    Below is a typical connection string:

    Server=127.0.0.1;Port=21050;

    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.

Generate the Schema

After you enter connection properties in the Add Adapter wizard, the Schema wizard is displayed.

  1. On the next page, Schema Information, select the Send Port that you have configured to use the Impala Adapter.
  2. If you have configured the CData Impala Adapter in a solicit-response send port, disable the One-Way option.
  3. In the Command Type menu, select Stored Procedure.
  4. Select the stored procedure from the menu and enter the values for the input parameters.
  5. Confirm the settings in the summary displayed by the wizard and click Finish to generate the schema.xsd file.
