+Creating Amazon Kinesis – Data Streams Data Source

The Amazon Kinesis – Data Streams connector reads records from the given data stream and Shard ID.

1. n the New Data Source page, select Input > Amazon Kinesis – Data Streams in the Connector drop-down list.
2. You can either:
   • Select  the Use Default Credentials Chain checkbox to use the default Access Key ID and Secret Key Access, or
   • Unselect the Use Default Credentials Chain checkbox and enter the Access Key ID and Secret Key Access

   

   NOTE: The Access Key ID and Secret Key Access from the AWS account can be configured in three places:

   • Two properties at the Streams.properties file which is available in the AppData folder of Panopticon Streams
     • connector.kinesis.datastreams.accesskeyid
     • connector.kinesis.datastreams.secretaccesskey

     If this is the used configuration, the Use Default Credentials Chain box is not displayed in the connector UI.

     mmm

     This is the recommended way to provide the credentials.

   • AWS credentials provider chain
     • Environment Variables - AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY
     • Credential profiles file at the default location - ~/.aws/credentials on Linux, macOS, or Unix, and C:\Users\USERNAME\.aws\credentials on Windows.

     

   • Dedicated fields in the connector

     Not the recommended configuration.

   NOTE: Prepend 'default:' for the elements falling under default namespace.

6. Click   to the fetch the schema based on the connection details. Consequently, the list of columns with the data type found from inspecting the first ‘n’ rows of the input data source is populated and the Save button is enabled.
7. You can also opt to load or save a copy of the column definition.
8. You can also opt to click   to add columns to the Amazon Kinesis – Data Streams connection that represent sections of the message. Then enter or select:
