Snap Views

View Description Examples of Upstream and Downstream Snaps
Input This Snap supports a maximum of one binary or document input view. When the input type is a document, you must provide a field to specify the path to the input prompt. The Snap requires a prompt, which can be generated either by the Amazon Bedrock Prompt Generator or any user-desired prompt intended for submission to the Anthropic Claude Messages API.
Output This Snap has at the most one document output view. The Snap provides the result generated by the Anthropic Claude Messages API. Mapper

Error handling is a generic way to handle errors without losing data or failing the Snap execution. You can handle the errors that the Snap might encounter when running the pipeline by choosing one of the following options from the When errors occur list under the Views tab. The available options are:

  • Stop Pipeline Execution Stops the current pipeline execution when the Snap encounters an error.
  • Discard Error Data and Continue Ignores the error, discards that record, and continues with the remaining records.
  • Route Error Data to Error View Routes the error data to an error view without stopping the Snap execution.

Snap execution Dropdown list
Select one of the three modes in which the Snap executes. Available options are:
