It is also a good idea to keep the number of partitions small (realatively).
It is also a good idea to keep the number of partitions small (relatively).
The more partitions there are, the more work that has to be done by the
replicators and other backend jobs and the more memory the rings consume in
process. The goal is to find a good balance between small rings and maximum

It is also important to determine how many zones the cluster should have. It is
recommended to start with a minimum of 5 zones. You can start with fewer, but
our testing has shown that having at least five zones is optimal when failures

The above process should be done to make a ring for each storage service
