Description Коренберг Марк 2022-05-03 22:40:45 UTC 
Opening (Creating) any RocksDB shows this in the log:

2022/05/04-03:33:21.189530 7f14b298eac0 Fast CRC32 supported: Not supported on x86

I think it is wrong. At least, CRC32 offloading SHOULD be enabled on all targets where it exists (I guess not only x86, but also AARCH64).

Regarding compression - I would enable them all. Except, possibly, bzip2.
Comment 1 Коренберг Марк 2022-05-03 22:48:10 UTC 
See:

https://tracker.ceph.com/issues/42293
https://tracker.ceph.com/issues/21603
https://tracker.ceph.com/issues/22534

Regarding AARCH64: it IS supported. And also on PPC architecture as well.
Comment 2 Коренберг Марк 2022-05-03 22:49:50 UTC 
Seems https://github.com/facebook/rocksdb/pull/2950 does not help.
Comment 3 Jonny Heggheim 2022-05-19 07:42:17 UTC 
How can Fast CRC32 be enabled? I have updated RocksDB to 7.2.2 for rawhide and fixed/enabled the compression.
Comment 4 Ben Cotton 2022-08-09 13:38:27 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora Linux 37 development cycle.
Changing version to 37.
