I want to change the replication factor on a running cluster without downtime. Can I do a rolling restart with the following change and expect everything to adjust?
# Original config
namespace ns1 {
replication-factor 3
memory-size 16G
default-ttl 86400
single-bin false
storage-engine memory
}
# New config
namespace ns1 {
replication-factor 2 # Changed from 3
memory-size 16G
default-ttl 86400
single-bin false
storage-engine memory
}
Does the answer apply to other namespace settings?
