[ceph-users] rgw: strong consistency for (bucket) policy settings?

Hi, while I don't currently use rgw, I still am curious about consistency guarantees. Usually, S3 has strong read-after-write consistency guarantees (for requests that do not overlap). According to https://docs.ceph.com/en/latest/dev/radosgw/bucket_index/ in Ceph this is also true for per-object ACLs. Is there also a strong consistency guarantee for (bucket) policies? The documentation at https://docs.ceph.com/en/latest/radosgw/bucketpolicy/ apparently does not say anything about this. How would multiple rgw instances synchronize a policy change? Is this effective immediate with strong consistency or is there some propagation delay (hopefully on with some upper bound)? Best regards Matthias
