one, written in front of the words MongoDB supports asynchronous data replication between different services to implement failover (failover, failover, failback) and redundancy (data redundancy). At the same time, only one service node (primary or master) supports writing. MongoDB supports two modes of replication: Master/slave, master-slave replication, roles include Master and Slave. Replica set, replica

Environment: MongoDB version: 2.4.6,replica SetDemand: Primary pressure is too high, expect secondary share reading pressureObjectiveFrom an application perspective, it is much like using replica Set and using a single MONGO. The default driver connects to the primary node and routes all read and write requests to the master node. However, you can also configure additional options by setting the driver's re

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. Deployment Diagram TheThe figure is a copy of so

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

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
