MongoDB cluster in Linux-replica set Environment Construction MongoDB replica sets are suitable for scenarios with fewer writes and more reads. You can use message queues for write control to reduce the pressure on highly concurrent writes. The Application Scenario of replica set should be selected based on the project requirements. If there is a high concurrency

Perhaps the first impression is a copy of the game, the game copy is to let each player have a separate game environment, the replication of this environment is a copy of the embodiment.

MongoDB replica set database split and version upgrade combatProblem descriptionThe replica set rs_1 all of the database services, and adding memory is no longer sufficient for application stress.Solution SolutionsConsider splitting the replica set rs_1 part of the database to Rs_2, and upgrade the database version to 2.6 at the same time.Architecture diagram650)

MongoDB Sharding Cluster is a horizontally scalable mode. It is very powerful when the data volume is large. I have been trying to study three roles to build a MongoDB Sharding Cluster: 1. Shard Server: mongod instance, used to store actual data blocks. In the actual production environment, a role of Shard Server can be assumed by one Replica Set of several machines to prevent single point of failure (spof) on the host. 2. Config Server: mongod instan

MongoDB supports failover and implementation redundancy across multiple machines through asynchronous replication. Only one machine is used for write operations at the same time in multiple machines, and because of this, MongoDB provides the assurance of data consistency. The machine that plays the role of primary can distribute the read operation to Slave.MongoDB high availability is divided into two types:Master-slave master-slave replicationYou only need to add the –master parameter when a se

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
