Execute Stored Procedures to Amazon Athena in BizTalk

Stored procedures implement Amazon Athena 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 Amazon Athena 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:

   AccessKey='a123';SecretKey='s123';Region='IRELAND';Database='sampledb';S3StagingDirectory='s3://bucket/staging/';

   Authenticating to Amazon Athena

   To authorize Amazon Athena requests, provide the credentials for an administrator account or for an IAM user with custom permissions: Set AccessKey to the access key Id. Set SecretKey to the secret access key.

   Note: Though you can connect as the AWS account administrator, it is recommended to use IAM user credentials to access AWS services.

   Obtaining the Access Key

   To obtain the credentials for an IAM user, follow the steps below:

   1. Sign into the IAM console.
   2. In the navigation pane, select Users.
   3. To create or manage the access keys for a user, select the user and then select the Security Credentials tab.

   To obtain the credentials for your AWS root account, follow the steps below:

   1. Sign into the AWS Management console with the credentials for your root account.
   2. Select your account name or number and select My Security Credentials in the menu that is displayed.
   3. Click Continue to Security Credentials and expand the Access Keys section to manage or create root account access keys.

   Authenticating from an EC2 Instance

   If you are using the CData Data Provider for Amazon Athena 2018 from an EC2 Instance and have an IAM Role assigned to the instance, you can use the IAM Role to authenticate. To do so, set UseEC2Roles to true and leave AccessKey and SecretKey empty. The CData Data Provider for Amazon Athena 2018 will automatically obtain your IAM Role credentials and authenticate with them.

   Authenticating as an AWS Role

   In many situations it may be preferable to use an IAM role for authentication instead of the direct security credentials of an AWS root user. An AWS role may be used instead by specifying the RoleARN. This will cause the CData Data Provider for Amazon Athena 2018 to attempt to retrieve credentials for the specified role. If you are connecting to AWS (instead of already being connected such as on an EC2 instance), you must additionally specify the AccessKey and SecretKey of an IAM user to assume the role for. Roles may not be used when specifying the AccessKey and SecretKey of an AWS root user.

   Authenticating with MFA

   For users and roles that require Multi-factor Authentication, specify the MFASerialNumber and MFAToken connection properties. This will cause the CData Data Provider for Amazon Athena 2018 to submit the MFA credentials in a request to retrieve temporary authentication credentials. Note that the duration of the temporary credentials may be controlled via the TemporaryTokenDuration (default 3600 seconds).

   Connecting to Amazon Athena

   In addition to the AccessKey and SecretKey properties, specify Database, S3StagingDirectory and Region. Set Region to the region where your Amazon Athena data is hosted. Set S3StagingDirectory to a folder in S3 where you would like to store the results of queries.

   If Database is not set in the connection, the data provider connects to the default database set in Amazon Athena.

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 Amazon Athena Adapter.
2. If you have configured the CData Amazon Athena 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.
