main technical indicators are storage switching function, data copy function, data snapshot function and so on. When one storage fails, another standby storage can be quickly switched to a storage non-stop.>>mongodb High-availability cluster configurationHighly available cluster, i.e. high

A cluster can have multiple query routers (replica sets) to offload client requests (load balancing).Second, config server: Configure the servers. The metadata for the cluster is saved (for example, on which shards the data is placed), and query router determines which shards to
