Several businesses use databases for multiple functions, such as managing, storing, and accessing information in a database for inventories, sales, customer service, etc. As the data requirements of the brands are growing with each passing year, the importance of using databases with high-end functionalities cannot be harped enough. 

When it comes to choosing a reliable database, Redis and MongoDB are the two names that are tough to ignore. Read along to find out the differences between these databases to make an informed decision. 

Introduction to Redis and MongoDB

Redis database or Remote Dictionary Server is an open-source data platform that supports the storage of different types and huge volumes of data with a functional velocity. Primarily, the database is popular due to its cache, rapid data storage, and message brokerage. Being an in-memory data structure server, the database can hold various values like sets, bitmaps, binary, hashed values, lists, sorted sets, and hyper logs. 

On the other hand, MongoDB is a NoSQL open-source database that accepts values in BSON format. The database is document-oriented, and it stores data in the form of documents and collections. The database has also overcome a few challenges and obstacles faced by organizations using traditional RDBMS. 

Database structure: MongoDB V/s Redis 

The database structure setups are different for Redis and MongoDB. The latter performs similarly to a relational database, using an expressive query language. It is schema-free, and users do not have to craft document structures. 

The former, on the other hand, makes use of key-value stores. It means that data is assigned to an associated and key value. The setup is wholly different from MongoDB, and Redis does not use columns and rows traditionally used with relational databases. 

While the key-value stores benefit most users, Redis takes a bit of time to get used to. Redis uses unique data structures like strings, bitmaps, sets, etc. 

Performance: MongoDB V/s Redis

Compared to MongoDB, Redis is faster because it is an in-memory database. The database management system is a great choice for building complex data structures. But MongoDB suits medium-sized businesses in need of a reliable database management system. It is simple to use and scalable. 

Since Redis is faster, its speed causes some drawbacks. Redis uses more RAM than MongoDB, and you can notice this for non-trivial data sets. 

Pricing: MongoDB V/s Redis

Redis and MongoDB are open-source, and therefore, they are free to use. But they both have limitations. Although Redis and MongoDB enable users to manage and store all kinds of data, you need to know a programming language properly. 

When it is about data management, some organizations benefit from paying for a platform that does not require any code. It makes it easier to optimize workflows and streamline data processing without learning a query language. 

Scalability: MongoDB V/s Redis

When it comes to scalability, both Redis and MongoDB score points. Therefore, they are worthwhile additions to any organization. However, there are a few differences. Redis is written in C, and it is available for OS X, Windows, BSD, and Linux. On the other hand, MongoDB is written in C++, and it is available for OS X, Windows, Solaris, and Linux.

Both Redis and MongoDB support various programming languages, such as C++, C, C~, Python, Java, and Scala. When thinking about scaling data management, users must consider all of this. 

Popularity: MongoDB V/s Redis 

MongoDB and Redis are open-source databases with a loyal community of users. The former hosts webinars and other events on the community page. The latter also boasts a thriving community where you can discuss new features with other users or even meet up in person. 

Several companies are using these tools. For instance, MongoDB is used by Stack, Lyft, and Uber. Weibo, GitHub, and Twitter use Redis. 

Programming language support: MongoDB V/s Redis 

Redis’s programming languages are C#, C, Crystal, Clojure, Java, Elixir, Dart, Haxe, Fancy, Lua, JavaScript (Node.js), MatLab Virtual Basic, Python, Pascal, Scheme, Objective-C, Ruby, OCaml, Swift, Rebol, etc. 

The several programming languages supported by MongoDB are Clojure, PHP, C, Erlang, C++, JavaScript, Groovy, Swift, Powershell, Perl, Smalltalk, Python, Scala, etc. 

Security: MongoDB V/s Redis 

MongoDB is particular about security, and it has several authentication protocols. For validating the users, the data is encrypted. Also, this database management system allows authority specification and access in which users are assigned role-based account control. It ensures improved security.

Redis also has strict authentication protocols, and these are followed before any command is executed. Furthermore, it offers access to users with password-based authentication. 

The bottom line

You need to assess the differences between Redis and MongoDB to choose. Ensure to take into account the needs of your organization so the database management system caters to your specific requirements.
