Replication Commands - ( Database and Collection Commands )

Replication is the process of copying data from one database to another in real-time. MongoDB replication allows you to create multiple copies of your database and keep them in sync with each other. In this page, we will discuss the replication commands available for MongoDB.

Syntax

The basic syntax for using replication commands in MongoDB is as follows:

rs.<command>

Here, rs signifies that the command is related to replication, and <command> is the name of the command that you wish to execute.

Example

Here is an example of a replication command in MongoDB:

rs.status()

This command is used to get the status of the replication set.

Output

The output of a replication command in MongoDB varies depending on the specific command being executed. However, most replication commands return a JSON object that contains information about the replicas in the set, including their status, members, and state.

Explanation

Replication commands in MongoDB are used to manage and monitor your replication sets. These commands allow you to perform tasks such as adding or removing replicas from the set, monitoring the replication lag, and getting the status of each replica in the set.

Use

Replication commands are used to manage and maintain a replication set in MongoDB. These commands are useful for ensuring that your data is safe and available at all times. By executing replication commands, you can monitor the health of your replicas and take appropriate action to resolve any issues that may arise.
