Redis vs DynamoDB
Redis is an open-source, in-memory data store used by millions of developers as a database, cache, streaming engine, and message broker.
Redis is popular for real-time applications that require low latency and high throughput. It is also commonly used for caching database queries, complex computations, API calls, and session state.
On the other hand, 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.
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.
REDIS VS DYNAMODB POPULARITY
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.
If you want to learn or use a database solely for its popularity among developers, you should learn and use Redis over DynamoDB.
Generally, Redis is more popular than DynamoDB. DB-ENGINES 2023 ranks Redis as the 6th most popular database and DynamoDB is ranked as the 16th most popular database.
According to a Stack Overflow survey of 2022, Redis is the 6th most popular database, it is used by 24.97% of professional developers.
On the other hand, DynamoDB is the 10th most popular database, it is used by 9.42% of professional developers according to the same survey.
Redis is also loved by many developers than DynamoDB. Redis has been the most loved database from 2017 to 2021
As of 2022, Redis is the second most loved database, it is loved by 71.04% of developers versus 28.96% of developers who dreaded it.
On the other hand, DynamoDB is loved by 53.63% of developers versus 46.37% of developers who dreaded it.
Ultimately, if your choice of which database to learn or use depends on popularity, you should learn Redis over DynamoDB.
REDIS VS DYNAMODB SALARY
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 programming language, the more likely you are of getting a higher salary.
Generally, DynamoDB developers earn higher salaries than Redis 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 whiles Redis developers get an average salary of $76,783 per year.
So, if the salary is your major incentive for learning a database technology, you should learn DynamoDB over Redis, because you are more likely to get a higher salary as a DynamoDB developer than as a Redis developer.
REDIS VS DYNAMODB WHICH ONE IS EASIER
Some database technologies can be learned more easily than others. Both Redis and DynamoDB use Key – Value store as a primary database.
But Redis is also a multi-model database, meaning that it supports a variety of database paradigms.
This makes Redis much easier than DynamoDB because Redis allows you to use a database paradigm that you are comfortable with.
If you are already familiar with the AWS ecosystems, you will find DynamoDB very easy to work with.
With DynamoDB, there are no servers to provision, patch, or manage, and no software to install, maintain, or operate.
The good news is that there are plenty of helpful resources for both Redis and DynamoDB to help you learn the Database technologies.
The Redis and AWS DynamoDB communities are very big, active, and helpful, in case you get stuck with something.
REDIS VS DYNAMODB PERFORMANCE
Both Redis and DynamoDB are high-performance databases. Redis and DynamoDB are Key – Value databases, 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.
Redis is an in-memory database and is designed to be extremely fast and efficient in handling large volumes of data.
On the other hand, Amazon DynamoDB guarantees consistent single-digit millisecond performance at any scale.
DynamoDB is 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.
FEATURES AND APPLICATIONS
Redis has many amazing features that make it a popular choice for many developers. It comes with a data structure server that supports strings, hashes, lists, sets, sorted sets, streams, and more.
Another great feature of Redis is that; it Keeps the dataset in memory for fast access, but it can also persist all writes to permanent storage to survive reboots and system failures.
It is a great fit for use cases that require real-time data processing and analytics.
Redis is used by companies such as Twitter, Pinterest, Craigslist, GitHub, Stack Overflow, Snapchat, and many others.
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, and 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.
REDIS VS DYNAMODB COST
Redis is an open-source database and can be used for free. However, it requires manual management and scaling.
Redis also offers a paid enterprise version with additional features and support.
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.
SHOULD I USE REDIS OR DYNAMODB
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 multi-model database that you can use for real-time data processing, caching, streaming engine, and as a message broker, you should learn Redis over DynamoDB.
If you want a high-paying database that you can use for caching, complex queries, real-time video streaming, and applications that require high concurrency, you should learn DynamoDB over Redis.
