Enable Ceph compression¶

RADOS Gateway supports server-side compression of uploaded objects using the Ceph compression plugins. You can manually enable Ceph compression to rationalize the capacity usage on the MCP cluster.

To enable Ceph compression:

1. Log in to any rgw node.

2. Run the radosgw-admin zone placement modify command with the --compression=<type> option specifying the compression plugin type and other options as required. The available compression plugins to use when writing a new object data are zlib, snappy, or zstd. For example:

   radosgw-admin zone placement modify \
     --rgw-zone default \
     --placement-id default-placement \
     --storage-class STANDARD \
     --compression zlib
   

   Note

   If you have not previously performed any Multi-site configuration, you can use the default values for the options except compression. To disable compression, set the compression type to an empty string or none.
