Difference Between Hadoop and MongoDB

MongoDB is a C++-based system, therefore it handles storage efficiently. Hadoop is a Java-based technology library that serves as the basis for data storage, access, and analysis. Hadoop optimizes space more effectively than MongoDB. MongoDB is a NoSQL database, whereas Hadoop processes data using SQL. Hadoop is a system for handling large amounts of data, whereas MongoDB is a repository kind.

Hadoop vs MongoDB

The main difference between Hadoop and MongoDB is that Hadoop is a platform for collecting and analyzing Big Data in a dispersed setting, whereas MongoDB is a NoSQL repository. MongoDB is a NoSQL database that focuses on documents. MongoDB collects information in a textual form that is similar to JSON. Hadoop is better suited for large-scale computational applications, whereas MongoDB is best suited for actual data extraction and smelting.

Hadoop is a public access platform developed by Apache that is used to hold, filter, and analyze massive amounts of data. Hadoop is developed in Java which is not an OLAP system (online analytical processing). It is employed in batch/offline computing. It is utilized by Facebook, Yahoo, Google, Twitter, LinkedIn, as well as numerous more companies. Furthermore, it may be upscaled increased by putting nodes in the network.

MongoDB is a free and public access NoSQL management information system. NoSQL is a system technology that is employed as a replacement to conventional relational database systems. MongoDB is a way of managing manuscript data, as well as storing and retrieving data. Mongo DB may be used by businesses for ad-hoc searches, archiving, bandwidth allocation, aggregating, server-side JavaScript implementation, and other capabilities.

Comparison Table Between Hadoop and MongoDB

Parameters of ComparisonHadoopMongoDB
Data Presentation StyleIt works with both organized and unorganized material.Only CSV or JSON formats are supported.
The goal of designIt is mostly intended to be a repository.Its purpose is to evaluate and handle enormous amounts of data.
ConstructedIt is a Java program.It is a C++ program.
Hardware CostsIt may be more expensive because it is a collection of different programs.Because it is a specific entity, it is less expensive.
DisadvantagesIt is heavily reliant on ‘NameNode,’ which might be a cause of the difficulty.Weak fault tolerance, resulting in data destruction on occasion.

What is Hadoop?

Hadoop is more than just a single program; it is a system with several interconnected infrastructures that support dispersed information collection and computation. The Hadoop environment is made up of these elements. Some of them are primary ingredients that serve as the framework’s base, while others are supplemental elements that offer more functionality to the Hadoop universe. 

Despite the fact that Hadoop is largely regarded as a fundamental facilitator of large datasets, there are still certain issues to address. These difficulties originate from Hadoop’s complicated ecosystem and the requirement for significant technical expertise to perform Hadoop operations. However, with the correct integrated solution and capabilities, the complication is massively diminished, making it easier to deal with. 

Hadoop has made a significant impact on the computer industry in less than a decade. This is due to the fact that it has eventually made predictive analytics a reality. Its uses range from site inspection analysis to fraud prevention and detection to financial applications. 

Furthermore, the capacity to obtain massive amounts of information and the knowledge acquired from processing this information effects improved legitimate business choices, such as the capacity to concentrate on the correct group of consumers, weed out or solve incorrect procedures, optimize floor transactions, offer improved search outcomes, undertake actionable insights, and so forth.

What is MongoDB?

MongoDB is a worldwide online cloud platform for modern apps. This best-in-class technology and recognized practices allow you to install centrally managed MongoDB throughout AWS, Google Cloud, as well as Azure. It also provides reliability, flexibility, and conformity with one of the most demanding data protection and confidentiality regulations. MongoDB Cloud is an integrated data solution that combines a worldwide database server, analytics, data mart, wireless, and app capabilities. 

MongoDB’s database schema is very elastic, allowing you to aggregate and retain data of various forms without sacrificing sophisticated search choices, internet connectivity, and evaluation and optimization. When you wish to constantly adjust the databases, there is no delay. This means you may focus more on getting your information to perform tougher instead of investing more effort in dealing with data for the system. 

Mongo is being used by some of the world’s largest corporations, with more than 50% of the Fortune 100 businesses using this fantastic NoSQL system technology. It has a thriving environment with over 100 collaborators and a large investor base that is persistently investing in innovation. MongoDB is an extremely helpful NoSQL system that is utilized by several of the globe’s largest organizations. 

Owing to some of MongoDB’s most advanced functionality, it provides organizations with a never-before-seen collection of functionality for parsing all of their unorganized information. As a result, individuals that are skilled and accredited in dealing with the fundamentals and sophisticated degrees of MongoDB technologies should anticipate their careers to skyrocket. MongoDB, because of its versatility and scalability, may be utilized for datasets such as social networking sites, video files, and on and on.

Main Differences Between Hadoop and MongoDB

  1. Hadoop is capable of large-scale analysis, but MongoDB is capable of real-time retrieval and automating.
  2. Hadoop is a Big Data system that can manage a wide range of Big Data needs, whereas MongoDB is a NoSQL database that can support CSV/JSON.
  3. Hadoop cannot accommodate geospatial information properly, however, MongoDB can analyze geospatial material thanks to its geospatial sorting capability.
  4. Hadoop prioritizes large bandwidth above zero latency, but MongoDB can manage information at a very low delay and offers real-time data processing.
  5. Hadoop is more expensive than MongoDB since it is a piece of programs, but MongoDB is less expensive because it is a complete unit.


MongoDB’s platform is used for real-time organizational functions that assist consumers and operational processes. Hadoop, on the other hand, obtains data from MongoDB and combines it with data from multiple sources to generate a computer learning algorithm, which MongoDB will employ for Real-Time Operational operations. 

Each of these systems has some of the same advantages over conventional RDBMSs, such as virtualization, parallel computing, MapReduce architectural style, and the ability to handle huge quantities of contextual information, and as open-source code, they are significantly less expensive options than their licensed counterparts. Because they are both designed to handle data across groups or terminals of commodity technology, there is also a significant reduction in equipment expenditures.
