preExtractionHookConfiguration

Provides the configuration information for invoking a Lambda function in Lambda to alter document metadata and content when ingesting documents into Amazon Q Business.

You can configure your Lambda function using the PreExtractionHookConfiguration parameter if you want to apply advanced alterations on the original or raw documents.

If you want to apply advanced alterations on the Amazon Q Business structured documents, you must configure your Lambda function using PostExtractionHookConfiguration.

You can only invoke one Lambda function. However, this function can invoke other functions it requires.
