Does Java Client API uploadSnowballObjects supports auto extraction?

[uni-hungching-chang]

Hi, I'm using Minio Java API uploadSnowballObjects() and I wonder if it supports auto extraction after uploaded to S3? I've tried including snowball-auto-extract=true into userMetadata or headers. After the API call, I observed a .tar file was successfully uploaded under bucketName/ but the .tar file was not automatically extracted. Any suggestions or feedbacks are appreciated!

First attempt: add snowball-auto-extract in userMetadata

            ObjectWriteResponse response = minioClient.uploadSnowballObjects(
                    UploadSnowballObjectsArgs.builder()
                            .bucket(bucketName)
                            .objects(objects)
                            .userMetadata(Map.of(
                                    "snowball-auto-extract", "true"))
                            .build());

Second attempt: add snowball-auto-extract in headers

            ObjectWriteResponse response = minioClient.uploadSnowballObjects(
                    UploadSnowballObjectsArgs.builder()
                            .bucket(bucketName)
                            .objects(objects)
                            .headers(Map.of(
                                    "snowball-auto-extract", "true"))
                            .build());

A file named snowball.-[SOME_NUMBER].tar was created under bucketName/
The Metadata of the uploaded file showed Key: x-amz-meta-snowball-auto-extract, Value: true,true

Java Minio client version: 8.5.4

headers.put("X-Amz-Meta-Snowball-Auto-Extract", "true"); is set by default. You don't need to set it manually.
