Replica Set basic Replica Set is a decentralized backup mode provided by mongodb (mongodb also provides master-slave deployment and sharding mode). Each mongod can be a master, A primary is automatically selected in the replica set, and the others are currently seconary. After the primary fails, a new primary is automatically elected. All mongod In the

An overviewA replica set is a set of Mongod instances that maintain the same set of data. The replica set contains multiple data hosting nodes and an optional quorum node. In a data hosting node, only one member is considered the primary node, while the other node is considered the secondary node.The primary device accepts all write operations, and the device can accept read operations but needs to set Rs.s

Mongodb distributed cluster (2. Replica set)Overview
Replica set is a type of master-slave replication. It is a master-slave replication that comes with the Failover function. It solves the disadvantages of the master-slave replication and does not require human intervention when the master server fails, the system automatically selects a new master server.

Storage Replicas (Storage Replica) is a Windows server technology that allows for synchronous replication of volumes between servers or clusters for disaster recovery. It also allows you to use asynchronous replication to create a failover cluster that spans two sites while keeping all nodes synchronized.Storage replicas support synchronous and asynchronous replication:
Synchronous replication maps data in a low-latency network site and a vol
