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 in the Amazon S3 User Guide.
This operation supports metadata that can be returned by GetObject,
in addition to
response metadata is supported so that the
typically an Lambda function, can provide the same metadata when it internally invokes
WriteGetObjectResponse is called by a customer-owned
Lambda function, the metadata returned to the end user
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
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 in the Amazon S3 User Guide.
For .NET Core this operation is only available in asynchronous form. Please refer to WriteGetObjectResponseAsync.
public abstract WriteGetObjectResponseResponse WriteGetObjectResponse( WriteGetObjectResponseRequest request )
Container for the necessary parameters to execute the WriteGetObjectResponse service method.
