Doc Text:
.Increased the default value for the `objecter_inflight_ops` option The default value for the `objecter_inflight_ops` option was changed from 1024 to 24576. The original default value was insufficient to support a typical Object Gateway workload. With this enhancement, larger workloads are supported by default.

Comment 16 Tiffany Nguyen 2018-08-30 02:09:45 UTC 
Verified with build 12.2.5-39, when query objecter_inflight_ops, it returns 1024.  
I'm expecting to see objecter_inflight_ops = 24576 instead.

[root@c04-h05-6048r ceph]# ceph -v
ceph version 12.2.5-39.el7cp (f12d44e46a54948a86dd27b16c77d97475ba2d4e) luminous (stable)
[root@c04-h05-6048r ceph]# ceph daemon client.rgw.c04-h05-6048r config get objecter_inflight_ops
{
    "objecter_inflight_ops": "1024"
}
Comment 22 Tiffany Nguyen 2018-08-31 19:24:22 UTC 
With build 12.2.5-42, objecter_inflight_ops is now set to 24576.

[root@c04-h01-6048r run]# ceph -v
ceph version 12.2.5-42.el7cp (82d52d7efa6edec70f6a0fc306f40b89265535fb) luminous (stable)
[root@c04-h01-6048r run]# ceph daemon client.rgw.c04-h01-6048r config get objecter_inflight_ops
