Created attachment 1337777 [details] rgw-log Description of problem: RGW compression is not working , zlib compression type is specified. Actual size and used size are same but in the log compression enabled messages are shown. Version-Release number of selected component (if applicable): ceph version 12.2.1-10.el7cp (5ba1c3fa606d7bf16f72756b0026f04a40297673) luminous (stable) How reproducible: 100% Steps to Reproduce: 1. Created default zone and enabled compression with "zlib" type 2. Created objects and checked used space of bucket. 3. Actual size and used size showing same value, not showing anything like compressed. 4. But in log, compression enabled messages are shown. Actual results: No Compression is happened. Expected results: Compression should have happened and Used space of the bucket should have been less than the actual bucket space.
