-===========
-Compression
-===========
-
-.. versionadded:: Kraken
-
-The Ceph Object Gateway supports server-side compression of uploaded objects,
-using any of Ceph's existing compression plugins.
-
-
-Configuration
-=============
-
-Compression can be enabled on a Zone's placement target by providing the
-``--compression=<type>`` option to the ``radosgw-admin zone placement modify``
-command.
-
-The compression ``type`` refers to the name of the compression plugin to use
-when writing new object data. Each compressed object remembers which plugin
-was used, so changing this setting does not hinder the ability to decompress
-existing objects, not does it force existing objects to be recompressed.
-
-This compression setting applies to all new objects uploaded to buckets using
-this placement target. Compression can be disabled by setting the ``type`` to
-an empty string or ``none``.
-
-For example::
-
-  $ radosgw-admin zone placement modify --rgw-zone=default --placement-id=default-placement --compression=zlib
-  {
-  ...
-      "placement_pools": [
-          {
-              "key": "default-placement",
-              "val": {
-                  "index_pool": "default.rgw.buckets.index",
-                  "data_pool": "default.rgw.buckets.data",
-                  "data_extra_pool": "default.rgw.buckets.non-ec",
-                  "index_type": 0,
-                  "compression": "zlib"
-              }
-          }
-      ],
-  ...
-  }
-
-.. note:: A ``default`` zone is created for you if you have not done any
-   previous `Multisite Configuration`_.
-
-
-Statistics
-==========
-
-While all existing commands and APIs continue to report object and bucket
-sizes based their uncompressed data, compression statistics for a given bucket
-are included in its ``bucket stats``::
-
-  $ radosgw-admin bucket stats --bucket=<name>
-  {
-  ...
-      "usage": {
-          "rgw.main": {
-              "size": 1075028,
-              "size_actual": 1331200,
-              "size_utilized": 592035,
-              "size_kb": 1050,
-              "size_kb_actual": 1300,
-              "size_kb_utilized": 579,
-              "num_objects": 104
-          }
-      },
-  ...
-  }
-
-The ``size_utilized`` and ``size_kb_utilized`` fields represent the total
-size of compressed data, in bytes and kilobytes respectively.
