Paxos-single-replica-limit 1 # Number of nodes where the replica count is automatically reduced to 1.įile /var/ log/aerospike/aerospike. In practice, most deployments use a data factor of 2 (one master data and one copy) Configuration of nf: # Aerospike database configuration file for use with systemd. The more copies, the higher the reliability, but the higher the write request that must go through all the data copies. replication factor is a configuration parameter that cannot exceed the number of cluster nodes. Each node in the cluster has a configuration file nf, and the namespace configuration parameters in each node configuration file must be consistent The bin key name limits the number of bytes to no more than 14 bytes
