AWS S3 Lifecycle Policies Not Transitioning Objects as Expected with Multipart Uploads
I'm building a feature where Hey everyone, I'm running into an issue that's driving me crazy... I'm trying to configure an S3 lifecycle policy to transition objects to Glacier after 30 days, but it seems like the policy is not working correctly for files uploaded using multipart upload. I've verified the policy is correctly applied to the bucket, and I can see the objects in the S3 console. However, the objects that were uploaded in parts are not transitioning as expected. I've checked the S3 event logs, but they don’t provide any insights regarding the lifecycle events. Here's how I'm defining the lifecycle policy: ```json { "Rules": [ { "ID": "TransitionToGlacier", "Status": "Enabled", "Prefix": "", "Transitions": [ { "Days": 30, "StorageClass": "GLACIER" } ], "Expiration": { "Days": 365 } } ] } ``` I'm using the AWS SDK for Python (Boto3) to upload files, which works fine. Here’s the code snippet I used for uploading: ```python import boto3 s3_client = boto3.client('s3') bucket_name = 'my-bucket' file_path = 'path/to/my_large_file.mp4' key = 'my_large_file.mp4' with open(file_path, 'rb') as data: s3_client.upload_fileobj(data, bucket_name, key) ``` The files are showing up in the S3 bucket correctly, but after 30 days, they are still in the S3 Standard storage class. I’ve also confirmed that the objects are not part of any other lifecycle rules that might prevent the transition. Has anyone encountered this scenario with multipart uploads and S3 lifecycle policies? Is there something specific I need to do for objects uploaded using multipart upload to ensure they transition correctly? Any help would be appreciated! What am I doing wrong? I recently upgraded to Python 3.10. Thanks for any help you can provide!
