b. Sharding

We can store a large data by distributing it to several servers connected to the application. If a server cannot handle such a  big data then there will be no failure condition. The term we can use here is “auto-sharding”.

A great advantage of MongoDB is that it is a horizontally scalable database. When you have to handle a large data, you can distribute it to several machines.

f. Ad-hoc Query Support

MongoDB has a very advanced feature for ad hoc queries. This is why we don’t need to worry about fore coming queries coming in the future.

g. Easy Environment Setup

It is easier to setup MongoDB then RDBMS. It also provides JavaScript client for queries.

h. Full Technical Support

Disadvantages Of MongoDB

Nothing is fully complete or perfect. In spite of having so many advantages, MongoDB to has some limitations. Let’s discuss some of them here.

a. Joins not Supported

MongoDB doesn’t support joins like a relational database. Yet one can use joins functionality by adding by coding it manually. But it may slow execution and affect performance.

b. High Memory Usage

MongoDB stores key names for each value pairs. Also, due to no functionality of joins, there is data redundancy. This results in increasing unnecessary usage of memory.

c. Limited Data Size

You can have document size, not more than 16MB.

d. Limited Nesting

You cannot perform nesting of documents for more than 100 levels.
This was all about Advantages Of MongoDB Tutorial. Hope you like our explanation.


Hence, we have covered all the advantages of MongoDB and disadvantages of MongoDB. Now we have got some understanding of MongoDB usability for us.

In further articles, we will learn to set up the environment for MongoDB. We will see it for Windows, Linux, and other operating systems. Furthermore, if you have any query, feel free to ask in a comment section.
