How is the master node elected for replica set failover? Can I manually interfere with the Dismounting of a master node.Officially, the number of replica sets is preferably an odd number. Why?How is the mongodb replica set synchronized? What happens if the synchronization is not timely? Will there be inconsistency?Will mongodb failover automatically happen for no

MongoDB replica setsAndAuto shardingThe simple configuration procedure is what we will introduce in this article. Many tutorials on the Internet have written replica sets and auto sharding (or sharding) together, which may be confusing for beginners, this is because a better auto sharding solution is to set each shard (shard) as a replica set ).

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 replication Sets

Initial Experience of MongoDB3.6 Replica Set Replica Set is called a Replica Set in China. Simply put, a copy of data is stored in multiple places. 1. Why should I use a replica set and when? Some people say that the storage of a piece of data occupies a large amount of extra space in multiple places, which is a waste.

Tags: style blog http io ar color OS using SPIn the MongoDB replica set, the primary node handles read and write requests from the client, and the backup node is responsible for mapping the master node's data.How the backup node works can be described roughly as the backup node polls the data operations on the master node on a regular basis, and then carries out these operations on its own copy of the data to ensure synchronization with the data of th

The election plays a very important role in the operation of the replica set. During the election, there is no master node in the replica set, and the client's reading request is unacceptable.
