In this article, I am going to briefly explain the DynamoD B database. Nowadays, depending on the needs of programmers, there are many tools tailored to the project on the Internet. The tools used in all projects include databases.
Introduction of DynamoDB:
Amazon DynamoDB is a database with a key, value. This database can provide millisecond performance on any scale. It is a fully managed and durable database with built-in security, backup and recovery and memory storage for internet-scale applications. DynamoDB can control more than 10 trillion requests a day and can support more than 20 million requests per second.
In other words, Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable functionality seamlessly.
DynamoDB database advantage:
DynamoDB database frees developers from problems preparing hardware and software, setting up and configuring databases and managing operations on databases. This technology fixes the complexities of scaling and partitions and divides your data using more device resources to meet the needs of performing operations on your inputs and outputs. It also automatically copies your data in several available areas (it will be reloaded automatically in case of disk or node failure).
2- Storage scale
Amazon DynamoDB is designed to allocate resources to a table of hundreds or even thousands of servers played around multiple regions, to meet your storage and power needs. There are no preset limits for the data that each table can store. Developers can store and retrieve any amount of data, and as the amount of data stored in your table grows, DynamoDB plays data on more servers.
Amazon DynamoDB offers very little delay. Because it’s built on Solid State Drives to help optimize performance even on a high scale. In addition, by not indexing all features, it reduces the cost of reading and writing operations and only runs on the main keys when writing indexing operations. Thereby reducing the delay in reading and writing operations. DynamoDB delays are predictable. Even with the growth of data sets, delays are sustained due to the distributed nature of data and routing algorithms.
Given that the system is kept on Amazon servers, it copies its data to at least 3 different data centers. As a result, the system can continue to operate and service data even in complex downtime scenarios.
Amazon DynamoDB is an incredibly flexible system that doesn’t force its users to have a specific data model or a specific compatibility model. DynamoDB tables do not have a fixed layout but instead allow each data to take a certain number of values.
DynamoDB is designed to maintain high performance predictably. It’s very affordable for workloads of any scale, from the smallest to largest program on an internet scale.
You can start with amazon DynamoDB free of charge, which makes 40 million requests a month free of charge.
