Ceph » rgw

The case is simple:

• storage classes is:

rgw zone placement configuration: radosgw-admin zone get --rgw-zone=default | jq '.placement_pools[] | select(.key=="default-placement")'

{
  "key": "default-placement",
  "val": {
    "index_pool": "default.rgw.buckets.index",
    "storage_classes": {
      "GLACIER": {
        "data_pool": "default.rgw.buckets.data",
        "compression_type": "lz4" 
      },
      "STANDARD": {
        "data_pool": "default.rgw.buckets.data" 
      }
    },
    "data_extra_pool": "default.rgw.buckets.non-ec",
    "index_type": 0
  }
}

• user use STANDARD class by default
• user set LC policy - move objects to GLACIER class
  

  <?xml version="1.0" ?>
  <LifecycleConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
      <Rule>
          <ID>Move_to_GLACIER</ID>
          <Prefix/>
          <Status>Enabled</Status>
          <Transition>
              <Days>0</Days>
              <StorageClass>GLACIER</StorageClass>
          </Transition>
      </Rule>
  </LifecycleConfiguration>
  

• when LC is complete, all objects will have a GLACIER class, but still not compressed, bucket stats diff:

I perform test:

• upload bunch of test data (git repos mostly) - with STANDARD class, then move to GLACIER class with LC

• upload this data again, to another bucket with --storage-class=GLACIER option - data is really compressed
