Similarities & Differences


The following are some key similarities between Redis and MongoDB:

  • They were both released in the same year, 2009.
  • Both are open source projects.
  • Compatibility – Windows, Linux, and OS operating systems are all supported.
  • Programming languages: C, C#, C++, Clojure, D, Dart, Erlang, Go, Haskell, Java, JavaScript, Lisp, Lua, MATLAB, Perl, PHP, Prolog, Python, Ruby, Scala, and Smalltalk are all supported.



Performance-wise, Redis is fine; however MongoDB is more efficient in terms of API usage. When it comes to selecting a database, additional information is required. Let’s look into the performance, speed, configuration, and other details of each database.

Let’s dive into the advantages and disadvantages of Redis and MongoDB


Advantages of Redis – Why to choose Redis

Redis system is the in-memory database valuable for cache, message brokering, and the improvement errands that require exceptional execution.

The Redis system is an in-memory database that is useful for caching, message brokering, and other tasks that need quick execution.

More information is provided below:

  1. Redis is an excellent caching solution. You’ll be able to create complex data structures and have a wide range of storage options with it.
  2. The establishment’s handle is straightforward, and the database is straightforward to keep.
  3. The structure is unstoppable. Despite the fact that the database adapts to massive amounts of data, the explicit key-value structure protects it from problems.
  4. The Redis system is the ideal choice for “hot data,” or data that needs to be processed fast. It can analyze up to 1GB of data at a time in this situation.
  5. It includes a powerful message transit system that can be easily replicated on several machines within a cluster.


Disadvantages of Redis

Redis, on the other hand, has a few flaws that you should be aware of. They’re all connected to the database’s in-memory structure.

The following are the basic components that Redis lacks:

  1. It fails to maintain encryption on the wire.
  2. Redis adheres to its policy of requiring a certain amount of capacity for every data.
  3. Within the database, there is no premise for isolating components and obligations.
  4. It’s tough to connect Redis to large cloud databases in large companies.
  5. This database necessitates the use of your structural abilities to plan ahead of time the sparing and organization of your data.


Advantages of MongoDB

On the other hand, the MongoDB system is frequently saved to disk, and it is referred to as a Personal memory capacity motor. As a result, the MongoDB database has amassed a number of benefits:

  1. MongoDB successfully addresses the issue of fetch and performance for determining the best configuration.
  2. It’s simple to obtain and utilize, thanks to the user-friendly JSON representation scheme.
  3. All of the essential features are built-in, including SSL, RBAC, and scale-out.


Disadvantages of MongoDB

In fact, when you try to use MongoDB for tasks that are more involved than simple prototyping, you’ll find that it has limitations.

  1. The MongoDB database’s unusual structure is also chaotic. As a result, in any instance of immediate and direct preparation, this technique has significant disadvantages.
  2. The MongoDB database still lacks a viable foundation for adjusting with copies.
  3. MongoDB is unable to maintain elements for official purposes in a long-term manner.


5 important differences when comparing MongoDB vs. Redis

When comparing MongoDB with Redis, there are five key differences to consider:

  1. Speed: Because Redis is an in-memory database, it is faster than MongoDB.
  2. RAM: For non-trivial data sets, Redis requires more RAM than MongoDB.
  3. Scalability: MongoDB outperforms Redis in terms of scalability.
  4. Storage: Redis is mostly used by businesses for key-value storage. Everything is stored in documents in MongoDB.
  5. Customer feedback: MongoDB and Redis have received mostly positive feedback.


MongoDB vs. Redis: Features and Benefits

Redis vs MongoDB Speed

In the duel between Redis and MongoDB, MongoDB is known for its great speed. MongoDB is simple to use and structured, therefore it doesn’t take much time and can be quick. The presence of fragmented elements in Redis’ internal structure, on the other hand, forces it to take longer to process.

Redis vs MongoDB Read Performance

If we are looking for Redis vs MongoDB performance, both databases are compute-bound. However, Redis manages to perform the same quality on one core, while MongoDB uses multiple cores to succeed. If we are comparing Redis vs MongoDB for caching, your Redis database can fly as fast as your cache!
However, everything comes at a cost, and the Redis framework pays for its superior performance by using significantly more RAM for storage.
In any event, MongoDB is a good fit for most medium-sized enterprises that need a robust database. It’s reasonably basic and straightforward to use, as well as extremely versatile, as previously stated.

Redis vs MongoDB: Configuration

The comparison of Redis and MongoDB based on YCSB measurement tests also found that Redis outperformed MongoDB.

MongoDB vs. Redis: Popularity

Both databases are free and open-source.

They each have a loyal following of users:

  • On MongoDB’s community page, there are usually webinars and other events.
  • Redis has a thriving community where customers may learn about current events and meet new people.
