Offered by Amazon Web Service (AWS), DynamoDB is a fully-managed NoSQL database which provides fast and predictable performance with seamless scalability. According to the latest Global NoSQL Database Market research reports, the CAGR status in the market will show a rise of +35% by 2025 in DynamoDB.
In one of our earlier articles, we discussed how DynamoDB is helping out the tech giants to attain their big billion-day sale successfully. This database system is being used by a number of popular organisations such as Lyft, Airbnb, Samsung, Toyota, among others. During the Prime Day of Amazon, DynamoDB served over 56 billion extra requests worldwide on Prime Day compared to the same day the previous week.
In this article, we will discuss the importance of DynamoDB and how it is gaining popularity among the developers.
How It Works
DynamoDB automatically spreads the data and traffic for a user’s table over a sufficient number of servers to handle the throughput and storage requirements, while maintaining consistent and fast performance. The core components of DynamoDB include tables, items, and attributes. Similar to other database systems, this database also stores adat in tables where each table contains zero or more items and each item is composed of one or more attributes.
Some of the intuitive features of this database are mentioned below
- Encryption At Rest: DynamoDB offers encryption at rest which helps in eliminating the operational burden and complexity involved in protecting sensitive data.
- Limitless Data: With DynamoDB, one can create database tables that can store and retrieve any amount of data and serve any level of request traffic.
- On-Demand Backup and Restore: DynamoDB provides an on-demand backup capability which allows a user to create full backups of the tables for long-term retention and archival for regulatory compliance needs.
- Point-in-Time Recovery: In this database, point-in-time recovery helps protect the tables from accidental write or delete operations. It can also restore that table to any point in time during the last 35 days.
- Time to Live: DynamoDB allows a user to delete expired items from tables automatically to help you reduce storage usage and the cost of storing data that is no longer relevant.
Why Use It?
DynamoDB can handle more than 10 trillion requests per day and can support peaks of more than 20 million requests per second. Here are some of the benefits of using this database mentioned below:
- Performance At Scale: DynamoDB global tables replicate the data across multiple AWS regions in order to give fast and local access to data for the globally distributed applications.
- No Servers To Manage: DynamoDB is serverless and it automatically scales tables up and down to adjust for capacity and maintain performance.
- Enterprise Ready: DynamoDB supports ACID transactions to enable a user to build business-critical applications at scale. It encrypts all data by default and provides fine-grained identity and access control on all the tables.
Is DynamoDB Better Than MongoDB
MongoDB and DynamoDB are two popular NoSQL databases. MongoDB has lots of interesting features such as the dynamic schemas which allow users to create records without first defining the structure — basically, it can be run anywhere. However, DynamoDB has been gaining popularity over MongoDB due to its serverless and easy-to-use nature as well as better security. MongoDB is less secured as compared to DynamoDB.
According to the Stack Overflow’s annual Developer Survey 2019, DunamoDB has secured the 9th position as the most loved database by the developers. With the help of DynamoDB, a user can perform a number of tasks, such as the users are able to build web applications that can automatically scale up and down, build interactive mobile and web apps with real-time updates, offline data access and data sync with built-in conflict resolution, build flexible and reusable microservices, and much more.
