DynamoDB vs MySQL

DynamoDB vs MySQL

DynamoDB is a fully managed serverless key-value NoSQL database designed to run high-performance applications at any scale.

DynamoDB is owned and offered by Amazon as part of their Amazon Web Services (AWS) portfolio.

DynamoDB offers built-in security, continuous backups, automated multi-Region replication, in-memory caching, and data import and export tools.

MySQL is an open-source relational database management system (RDBMS). It is fast, reliable, scalable, and easy to use.

MySQL is a very powerful database system, it was originally developed to handle databases quickly. It is one of the most popular databases used by many big companies.

One of the major differences between MySQL and DynamoDB is that MySQL is a relational database system that uses the SQL language while DynamoDB is a NoSQL, Key – Value, and Document-based database.

Comparing databases and choosing which one to learn or use for your next project can be tricky.

There are many factors to consider in order to choose the right database for the job you want to do.

Popularity, opportunities, type of projects, salaries, resources, learning curve, etc. are some of the factors that many people consider when comparing databases and choosing which one to learn or use.

Here are some of the comparisons and considerations you should make when choosing a Database.


Comparing the popularity of databases is not an easy task. Although the primary use of databases is to store and retrieve data, many databases are different in how they approach data storage and retrieval.

As a result, different fields and projects may require the use of different databases. This is why many companies use more than one database.

If you want to learn or use a database solely for its popularity among developers, you should learn and use MySQL over DynamoDB.

Generally, MySQL is more popular than DynamoDB. As of June 2023, DB-ENGINES ranks MySQL as the 2nd most popular database and DynamoDB is ranked as the 15th most popular database.

According to a Stack Overflow survey of 2022, MySQL is the most popular database, it is used by 46.85% of developers.

On the other hand, DynamoDB is the 11th most popular database, it is used by 8.26% of developers according to the same survey.

Ultimately, if your choice of which database to learn or use depends on popularity, you should learn MySQL over DynamoDB.


Another popular criterion that many people use to compare databases and as an incentive to learn a new database technology is salary.

Salaries for developers differ from one company to the other and from one country to the other.

Experience is another factor that comes into play as far as salaries are concerned.

The more experience you have with a certain technology or database, the more likely you are of getting a higher salary.

Generally, DynamoDB developers earn higher salaries than MySQL developers.

According to a Stack Overflow survey of top-paying databases, DynamoDB is the highest-paying database of 2022.

DynamoDB developers get an average salary of $94,244 per year while MySQL developers get an average salary of $55,455 per year.

So, if the salary is your major incentive for learning a database technology, you should learn DynamoDB over MySQL.

You are more likely to get a higher salary as a DynamoDB developer than as a MySQL developer.


Some database technologies can be learned more easily than others. DynamoDB is very easy to work with.

With DynamoDB, there are no servers to provision, patch, or manage, and no software to install, maintain, or operate.

DynamoDB’s API is relatively simple and easy to use, with a limited set of operations and no complex SQL queries to master.

If you are already familiar with the AWS ecosystems, you will find DynamoDB very easy to work with.

MySQL can be more complex to set up and administer than DynamoDB, Using MySQL requires a basic to a good understanding of the SQL language.

MySQL may be easier to use for developers who are already familiar with SQL and relational data modeling.

The good news is that there are plenty of helpful resources for both MySQL and DynamoDB to help you learn the Database technologies.

The MySQL and AWS DynamoDB communities are very big, active, and helpful, in case you get stuck with something.


Both MySQL and DynamoDB are high-performance databases. DynamoDB is a Key – Value database, this provides advantages that other databases may not have.

Key-value databases are highly partitionable and allow horizontal scaling at scales that other types of databases cannot achieve.

Amazon DynamoDB guarantees consistent single-digit millisecond performance at any scale.

DynamoDB is also a fully managed NoSQL database that can handle petabyte-scale workloads and can automatically scale up or down based on the traffic and usage patterns.

MySQL, on the other hand, is a more traditional relational database that is optimized for complex queries and data manipulation.

It offers a rich set of features, including transaction support, complex queries, and robust data consistency.

MySQL is known for its strong performance in traditional relational database use cases. With proper configuration and optimization, MySQL can handle high concurrent workloads efficiently.

MySQL is a good fit for applications with well-defined schemas and complex relationships between data.

It is often used for traditional web applications, content management systems, and e-commerce platforms.

MySQL provides strong consistency guarantees and is known for its reliability and mature ecosystem of tools and libraries.



DynamoDB is also popular in the enterprise world. Being part of the AWS portfolio, DynamoDB provides the simplicity that small startups require and the robustness required by big companies.

DynamoDB offers built-in security, automated multi-Region replication, in-memory caching, continuous backups, data modeling tools, and more.

DynamoDB is used by companies such as Disney, Tinder, Netflix, Zoom, Dropbox, Nike, Samsung, Snapchat, Airbnb, Comcast, Lift, and many others.


MySQL is a well-established and widely used relational database management system (RDBMS) that follows the ACID (Atomicity, Consistency, Isolation, Durability) principles.

It ensures data integrity and provides support for complex relationships between data through the use of tables, columns, and relationships.

MySQL also delivers a complete set of native, fully integrated replication technologies for high availability and disaster recovery.

Replication enables data redundancy, load balancing, and failover in case of hardware or network failures.

MySQL has a large and active community of developers and users, which means there is a vast amount of resources, tutorials, and community support available.

It also benefits from a wide range of third-party tools, libraries, and frameworks that integrate seamlessly with MySQL.

MySQL is used by companies such as Youtube, Facebook, PayPal, LinkedIn, Twitter, eBay, Cisco, Verizon, Uber, Shopify, Netflix, Github, Walmart, Booking.com, Flipkart, Tencent, Alibaba, Paytm, Bank of America, WordPress, Wikipedia, and many others.a


MySQL is an open-source database, which means that it is free to use and there are no licensing costs associated with it.

However, you will need to pay for the infrastructure to host the database, which may include costs for servers, storage, and bandwidth.

You may also need to pay for additional services like monitoring, backup, and maintenance.

DynamoDB is a fully managed database and is billed based on usage, storage, and throughput.

It offers a free tier with limited usage and low cost for small workloads, but can get expensive for large-scale workloads.


Once you have compared the databases and evaluated all the factors, you can choose which database technology to learn or use depending on the factors that are on your side and what you want to build.

If you want a popular, open-source relational database that you can use for complex queries, full-text search, advanced datatypes, and more, you should use MySQL.

If you want a NoSQL database that you can use for caching, complex queries, real-time video streaming, and applications that require high concurrency, you should use DynamoDB.
