Now that we have seen MongoDB features, let’s see the advantages and disadvantages of MongoDB. It is a non-relational database. Hence, it is good to compare with RDBMS and see where it meets our expectations. Our aim in advantages of MongoDB tutorial is to see some of the main MongoDB benefits and limitations of MongoDB.
So, let’s study Advantages of MongoDB | Disadvantages of MongoDB.
2. Advantages Of MongoDB
There are many great features inbuilt with MongoDB. As compared to RDBMS, so let’s discuss MongoDB Benefits.
a. Flexible Database
We know that MongoDB is a schema-less database. That means we can have any type of data in a separate document. This thing gives us flexibility and a freedom to store data of different types.
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”.
c. High Speed
MongoDB is a document-oriented database. It is easy to access documents by indexing. Hence, it provides fast query response. The speed of MongoDB is 100 times faster than the relational database.
d. High Availability
MongoDB has features like replication and gridFS. These features help to increase data availability in MongoDB. Hence the performance is very high.
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
h. Full Technical Support
MongoDB Inc. provides professional support to its clients. If there is any problem, you can directly reacha MongoDB client support system.
3. 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.
