Static One-Way Send Port
This section provides step-by-step instructions for creating, configuring, and testing a static one-way send port using the CData BizTalk Adapter for Apache Impala.
Using One-Way Send PortsYou can use static one-way send ports to execute updategrams, SQL commands, and stored procedures. Send ports are useful for operations that modify Apache Impala data but do not have any response data. Typically, this would be DELETE or UPDATE SQL commands or updategrams, and occasionally stored procedure operations.
If you want to trigger actions that will return a response, such as executing SELECT commands or retrieving the _ids of records that you created, use a Static Solicit-Response Send Port.
Create and Configure the One-Way Send Port
Create a static one-way send port and configure it to use the Apache Impala adapter as its transport type.
- If you have not already done so, open your BizTalk application in the BizTalk Administration Console.
- In the node for your BizTalk application, right-click Send Ports and select New -> Static One-Way Send Port. The send port properties dialog is displayed.
- In the Name menu, enter a name for the send port.
- In the Type menu, select CData.ApacheImpala.
- In the Send Pipeline menu, select the default option, PassThruTransmit.
Configure the Adapter
Define the command that the adapter will execute in the Transport Properties dialog.
- In the send port properties, click the Configure button. The CData.Apache Impala Transport Properties dialog is displayed.
- In the CommandType property, select the command type you want.
- If you want to execute an SQL command, enter the command in the SQL Command box.
Configure the Connection to Apache Impala
Configure credentials and other properties required to connect to Apache Impala in the Connection String Options dialog.
- In the send port properties dialog, click Configure. The adapter properties dialog is displayed.
- Click the button in the Connection String property.
- Click the box in the Connection String property. The Connection String Options dialog is displayed.
- Enter connection properties. A typical connection string is below:
- Click Test Connection to verify the values and test connectivity.
After you connect successfully and define the command the adapter will execute, the send port is ready for use. See the following example to walk through a simple application that uses a one-way send port.
Create Filters to Route BizTalk Messages Through an Application
To associate a send port with the messages you want, create a filter rule in the Filters section of the properties for that send port. Messages matching the criteria will be routed to the send port. See the following example to filter on a receive location.
In the example, filters are used to move the updategram from the receive location to the send port. See the following section for more information on filters.
Example: Execute Updategrams with a One-Way Send Port
This section shows how to use a one-way send port in a simple application. The application reads updategram commands contained in a file and executes the commands, following the procedure below.
- A one-way receive location picks up the XML document containing the updategram.
- The receive location creates a BizTalk message containing the results of the command.
- A one-way send port filters on the URI of the receive location. The document is routed to the one-way send port.
- The send port executes the updategram command.
As in the preceding example, the followings steps show how to set up a receive location to read updategrams from a file and use a send port to execute the commands:
- Create and configure a static one-way receive location. Use the File transport type. You can follow the same procedure to configure a Apache Impala adapter in Static One-Way Receive Location.
- Create a static one-way send port.
- In the send port properties, click Filters.
- In an empty property, set the following values:
Property Select BTS.InboundTransportLocation from the menu. Value Enter the URI of the newly created one-way receive location.
