// This operation is not supported by directory buckets. Passes transformed
// objects to a GetObject operation when using Object Lambda access points. For
// information about Object Lambda access points, see Transforming objects with
// Object Lambda access points (https://docs.aws.amazon.com/AmazonS3/latest/userguide/transforming-objects.html)
// in the Amazon S3 User Guide. This operation supports metadata that can be
// returned by GetObject (https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetObject.html)
// , in addition to RequestRoute , RequestToken , StatusCode , ErrorCode , and
// ErrorMessage . The GetObject response metadata is supported so that the
// WriteGetObjectResponse caller, typically an Lambda function, can provide the
// same metadata when it internally invokes GetObject . When WriteGetObjectResponse
// is called by a customer-owned Lambda function, the metadata returned to the end
// user GetObject call might differ from what Amazon S3 would normally return. You
// can include any number of metadata headers. When including a metadata header, it
// should be prefaced with x-amz-meta . For example, x-amz-meta-my-custom-header:
// MyCustomValue . The primary use case for this is to forward GetObject metadata.
// Amazon Web Services provides some prebuilt Lambda functions that you can use
// with S3 Object Lambda to detect and redact personally identifiable information
// (PII) and decompress S3 objects. These Lambda functions are available in the
// Amazon Web Services Serverless Application Repository, and can be selected
// through the Amazon Web Services Management Console when you create your Object
// Lambda access point. Example 1: PII Access Control - This Lambda function uses
// Amazon Comprehend, a natural language processing (NLP) service using machine
// learning to find insights and relationships in text. It automatically detects
// personally identifiable information (PII) such as names, addresses, dates,
// credit card numbers, and social security numbers from documents in your Amazon
// S3 bucket. Example 2: PII Redaction - This Lambda function uses Amazon
// Comprehend, a natural language processing (NLP) service using machine learning
// to find insights and relationships in text. It automatically redacts personally
// identifiable information (PII) such as names, addresses, dates, credit card
// numbers, and social security numbers from documents in your Amazon S3 bucket.
// Example 3: Decompression - The Lambda function S3ObjectLambdaDecompression, is
// equipped to decompress objects stored in S3 in one of six compressed file
// formats including bzip2, gzip, snappy, zlib, zstandard and ZIP. For information
// on how to view and use these functions, see Using Amazon Web Services built
// Lambda functions (https://docs.aws.amazon.com/AmazonS3/latest/userguide/olap-examples.html)
// in the Amazon S3 User Guide.
