When you DELETE an object, all versions remain in the bucket and MinIO adds a delete marker, as shown below:

![delete](https://raw.githubusercontent.com/minio/minio/master/docs/bucket/versioning/versioning_DELETE_versionEnabled.png)

MinIO's Object Lambda, enables application developers to process data retrieved from MinIO before returning it to an application. You can register a Lambda Function target on MinIO, once successfully registered it can be used to transform the data for application GET requests on demand.
