Thanks Sam,
That's great. I'm trying to understand a bit of RADOS internals and I
went through architecture wiki. Yet unclear about some points.
Where does RADOS store the list of objects (object metadata)? According
to RADOSGW docs S3 bucket listing is available, so it must be stored
somewhere.
Thanks,
Rustam.

Hi,
We need to store ~500M of small files (<1MB) and we were looking to RadosGW
solution. We expect about 20 ops/sec (read+write). I'm trying to understand
how Monitoring nodes store Crush maps and what are the limitations.
For instance, is there any recommended max number of objects per Monitoring
node? Does adding more monitoring nodes will help to scale number of small
files and iops (assuming that OSDs not a bottleneck)?
No, the number of objects is unrelated to the monitors, so 3 monitors
should suffice in your case.

Many thanks,
Rustam.
