![MongoDB Database]()
Introduction
In this article, we will learn about MongoDB (one of the most popular and fastest-growing no SQL databases).
Databases are important for every internet and enterprise application.
Scale, speed, and fast application development have brought on a new breed of databases that broadly turned to no SQL databases.
What is Mongo Database?
MongoDB is an open-source document database that provides high performance, high availability, and automatic scaling.
Features of Mongo Database
- MongoDB has no schema, no tables, no rows, no columns, and certainly no relationships among tables.
- In MongoDB, we have single-document write scope; a document lives in a collection, but updating documents occurs one at a time. So if any locking is needed, then it would be much simpler, there is no need to extend locks across collections, and there are no relationships to enforce.
- Mongo also offers a special collection called a capped collection that has a fixed size and automatically overwrites old documents.
High Performance
MongoDB provides high-performance data persistence. In particular:
- Support for embedded data models reduces the I/O activity of the database systems.
- Indexes support faster queries and can include keys from embedded documents and arrays.
High Availability
To provide high availability, MongoDB’s replication facility, called replica sets, provides:
- automatic failover.
- data redundancy.
A replica set is a group of MongoDB servers that maintain the same data set, providing redundancy and increasing data availability.
Automatic Scaling
MongoDB provides horizontal scalability as part of its core functionality.
- Automatic sharding distributes data across a cluster of machines.
- Replica sets can provide eventually consistent reads for low-latency high throughput deployments.
