The client interface in Swarm consists of:
policy.lifecyclesetting at the cluster-levelPolicy-Lifecycleheader on a domainPolicy-Lifecycleheaders on a bucket.
The evaluated policies are returned via Policy-Lifecycle-Evaluated headers on domains, buckets, and objects using GET/HEAD requests. For named objects, the verbose query argument is required to see those headers. The gateway supports S3 lifecycle policies as described in the S3 documentation.
Swarm UI supports the above cluster setting just like any existing cluster setting. In the Content Portal, a customer can edit at the domain and bucket levels.
