> Last year, AWS S3 supported conditional writes (although GCP has supported it
> for a long time). Conditional reads have been supported for a while.
> This feature has been used by some applications (databases on s3). One blog
> (https://www.morling.dev/blog/leader-election-with-s3-conditional-writes/)
> also implemented a PoC of leader election based on s3 conditional writes.
> HDDS-10656 has already implemented a atomic rewrite key feature, but we need
> to check whether we can use this feature.
> A short design doc will be useful. We can separate this tickets to multiple
> smaller tickets
> # Conditional reads (HeadObject / GetObject)
> # Conditional copy (CopyObject)
> # Conditional writes
