1. Replica setThe master-slave deployment of MongoDB is commonly used in the form of a replica set (replica set). Replica set is a set of multiple Mongod instances that comprise a group of groups, including a master primary, and multiple from secondary. The advantage of this one master multi-slave approach is that Mong

Mongodb replica set priority settings, mongodb replica priorityWhen you set a mongodb replica set, the Primary node, second node, and arbitration node may have unbalanced resource configurations (CPU or memory). Therefore, some nodes must not be Primary.We know mongodb settings:In addition to the arbitration node, each other node has a priority. You can manually

Principles of MongoDB replica set (I) and principles of mongodb Replication References Official Website: www.mongodb.org Chinese community: www.mongoing.com Online Tutorial: https://university.mongodb.com/ Mongodb supports the traditional master-slave architecture. There is no automatic failover function. You must specify the master and slave. We recommend that you use the replica set architecture, which is
