A replica set (replica sets) is an additional copy of the data that is the process of synchronizing data across multiple servers, which provides redundancy and increases data availability, and enables recovery of hardware failures and outage services through replication sets. Benefits of

MongoDB cluster building (master-slave replication, replica and) (5), mongodb master-slaveVi. Architecture ManagementMongodb master-slave clusters are divided into two types:1: master-Slave replication (master-Slave) -- The Slave server will not automatically change to the master server. You need to set the Slave serve

Features and benefits of MongoDB replication set Features of the replica set: n Nodes of a cluster Any node can be used as the master node All write operations are on the primary node Auto Fail-Ov

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 spec

Mongodb distributed cluster (1. Master-slave replication), mongodb master-slaveUnderstanding of distributed Clusters There are many explanations on the concept of distributed clusters. I prefer "distributed clusters" as two concepts, that is, distributed is one concept and cluster is another. Distributed is to divide an entire system into multiple parts and deplo

MongoDB Data Replication shard I. MongoDB introduction: MongoDB is a high-performance, open-source, and non-pattern document-based database. It is a popular NoSql database. It can be used in many scenarios to replace traditional relational databases or key/value storage methods. It can easily be combined with JSON data

In practice, we will explain how to build MongoDB and master-slave replication. Because there is only one server, you can only modify the port number to implement the master-slave MongoDB, instead of using multiple servers. In practice, we will explain how to build MongoDB and master-slave

CopyMongoDB replication is important, especially now that the storage engine does not support click Persistence. Not only can replication be used to deal with failover, data integration, but also read extensions, hot backups, or data sources as offline batches. 1. master-Slave copyingMaster-slave replication is the most common way of

I will talk about the replica set in the previous phase. The primary features of the replica set are embodied in two aspects: 1. the replica set does not have a specific primary database. 2. If there is a fault such as a crash, the cluster selects a database as the primary database, which provides the automatic fault recovery function. Next we will perform the following operations: in the folder, copy mongodb1_db2 I will talk about the replica set in the previous phase. The primary features of t

Master-slave replication is a feature of MongoDB databases. It uses data backup to improve database disaster tolerance. However, because master-slave replication cannot automatically implement failover, Mon Master-slave replication is a feature of MongoDB databases. It uses
