  MongoDB Architecture MongoDB is a popular NoSQL document-oriented database management system, known for its flexibility, high performance, high availability, and multi-storage engines. The term NoSQL means non-relational. It means that MongoDB isn’t based on a table-like relational database structure. It is used by Adobe, Uber, IBM, and Google. In this article, we will delve into the MongoDB architecture, exploring its key components and how they work together. Key Features of MongoDB:- Document-oriented Database Stores data in BSON-like documents. Schema Less database. It provides horizontal scalability with the help of sharding. It provides high availability and redundancy with the help of replication. It allows one to perform operations on the grouped data and get a single result or computed result. It has very high performance. MongoDB Architecture and its Components:- MongoDB’s architecture design involves several important parts that work together to create a strong and fle...

 MySQL Replication Switchover: Step-by-Step Guide MySQL replication is a powerful feature that allows you to create redundant copies of your database for improved availability and scalability. In certain scenarios, it becomes necessary to switch the roles of the master and slave servers in a replication setup. This article will guide you through the process of performing a MySQL replication switchover, ensuring a smooth transition without any data loss. Let’s dive into the step-by-step instructions. I have tow node one is master node and another is slave node.Given below details:- Current Master: 192.168.70.10 Current Slave : 192.168.70.11 Verifying the Replication:- Before initiating the switchover, it’s important to verify that replication is functioning correctly on the current Slave server (192.168.70.11). Execute the following queries to ensure the replication status: mysql> show slave status\G This command displays the slave’s status, including information such as replicat...

Mysql Commercial Mysqlbackup:How to take Differential or Incremental Backup and resotre using mysqlbackup utility in mysql 8.0.37 enterprise edition Incremental vs Differential Backup:- The main difference between incremental and differential backups is how they save space and time by storing only changed files. However, the effectiveness of incremental backups is very different from differential backups. Before we dive into the differences between Incremental and Differential backups let’s review Full Backups.  Are you still using Full Backups? In its simplest form, a full backup is the starting point for both Incremental and Differential backup strategies. A full backup, of course, backs up all the data on a partition or disk by copying all disk sectors with data to the backup image file.  A full backup is time-consuming and requires a lot of space, it’s usually used as part of a backup plan with long intervals, like once a week or a month. During this time, if anything goes...
