-----------------------------------
Summary: S3 tag support on write
Key: ARROW-16746
URL: https://issues.apache.org/jira/browse/ARROW-16746
Project: Apache Arrow
Issue Type: Improvement
Reporter: André Kelpe
S3 allows tagging data to better organize ones data
([https://docs.aws.amazon.com/AmazonS3/latest/userguide/object-tagging.html)]
We use this for efficient downstream processes/inventory management.
Currently arrow/pyarrow does not allow tags to be added on write. This is
causing us to scan the bucket and re-apply the tags after a pyrrow based
process has run.
I looked through the code and think that it could potentially be done via the
metadata mechanism.
The tags need to be added to the CreateMultipartUploadRequest here:
