Amazon DynamoDB: A Complete Guide To NoSQL Databases
Amazon DynamoDB fully managed, serverless, NoSQL database has single-digit millisecond speed at any scale.
What is Amazon DynamoDB?
You can create contemporary applications at any size with DynamoDB, a serverless NoSQL database service. Amazon DynamoDB is a serverless database that scales to zero, has no cold starts, no version upgrades, no maintenance periods, no patching, and no downtime maintenance. You just pay for what you use. A wide range of security controls and compliance criteria are available with DynamoDB. DynamoDB Global Tables is a multi-region, multi-active database with a 99.999% availability SLA and enhanced resilience for globally dispersed applications. Point-in-time recovery, automated backups, and other features support DynamoDB dependability. You may create serverless event-driven applications with Amazon DynamoDB streams.
Use cases
Create software programs
Create internet-scale apps that enable caches and user-content metadata, which call for high concurrency and connections to handle millions of requests per second and millions of users.
Establish media metadata repositories
Reduce latency with multi-Region replication between AWS Regions and scale throughput and concurrency for media and entertainment workloads including interactive content and real-time video streaming.
Provide flawless shopping experiences
When implementing workflow engines, customer profiles, inventory tracking, and shopping carts, use design patterns. Amazon DynamoDB can process millions of queries per second and enables events with extraordinary scale and heavy traffic.
Large-scale gaming systems
With no operational overhead, concentrate on promoting innovation. Provide player information, session history, and leaderboards for millions of users at once when developing your gaming platform.
Amazon DynamoDB features
Serverless
You don’t have to provision any servers, patch, administer, install, maintain, or run any software when using Amazon DynamoDB. DynamoDB offers maintenance with no downtime. There are no maintenance windows or major, minor, or patch versions.
You only pay for what you use using DynamoDB’s on-demand capacity mode, which offers pay-as-you-go pricing for read and write requests. With on-demand, DynamoDB maintains performance with no management and quickly scales up or down your tables to accommodate capacity. Additionally, when there is no traffic or cold starts at your table, it scales down to zero, saving you money on throughput.
Amazon DynamoDB NoSQL
NoSQL
DynamoDB is a NoSQL database that outperforms relational databases in performance, scalability, management, and customization. DynamoDB supports several use cases with document and key-value data types.
DynamoDB does not offer a JOIN operator, in contrast to relational databases. To cut down on database round trips and the amount of processing power required to respond to queries, advise you to denormalize your data model. DynamoDB is a NoSQL database that offers enterprise-grade applications excellent read consistency and ACID transactions.
Fully managed
DynamoDB is a fully managed database service that lets you focus on creating value to your clients. It handles hardware provisioning, security, backups, monitoring, high availability, setup, configurations, and more. This guarantees that a DynamoDB table is immediately prepared for production workloads upon creation. Without the need for updates or downtime, Amazon DynamoDB continuously enhances its functionality, security, performance, availability, and dependability.
Single-digit millisecond performance at any scale
DynamoDB was specifically designed to enhance relational databases’ scalability and speed, achieving single-digit millisecond performance at any scale. DynamoDB is designed for high-performance applications and offers APIs that promote effective database utilization in order to achieve this scale and performance. It leaves out aspects like JOIN operations that are ineffective and do not function well at scale. Whether you have 100 or 100 million users, DynamoDB consistently provides single-digit millisecond performance for your application.
What is a DynamoDB Database?
Few people outside of Amazon are aware of the precise nature of this database. Although the cloud-native database architecture is private and closed-source, there is a development version called DynamoDB Local that is utilized on developer laptops and is written in Java.
You don’t provision particular machines or allot fixed disk sizes when you set up DynamoDB on Amazon Web Services. Instead, you design the database according to the capacity that has been supplied, which includes the number of transactions and kilobytes of traffic that you want to accommodate per second. A service level of read capacity units (RCUs) and write capacity units (WCUs) is specified by users.
As previously mentioned, users often don’t call the Amazon DynamoDB API directly. Rather, their application will incorporate an Amazon Web Services, which will manage the back-end interactions with the server.
Denormalization of DynamoDB data modeling is required. Rethinking their data model is a difficult but manageable step for engineers accustomed to working with both SQL and NoSQL databases.
