Hello,
I have a 3 DC octopus Multisite setup with bucket sync policy applied.
I have 2 buckets where I’ve set the shard 24.000 and the other is 9.000 because they want to use 1 bucket but with a huge amount of objects (2.400.000.000 and 900.000.000) and in case of multisite we need to preshard the buckets as it is in the documentation.
Do I need to fine tune something on the syncing to make this query faster?
This is the output after 5-10 minutes query time not sure is it healthy or good or not to be honest, haven’t really find any good explanation about the output in the ceph documentation.
>From the master zone I can’r reallt even query because timed out, but in secondary zone can see this:

Hope I can find some expert in the multisite area 😊
Thank you in advance.
