Users don’t make DynamoDB API calls directly. Users can also specify a service level of write capacity units (WCUs) and read capacity units (RCUs). With this, you can manage as to how many kilobytes of traffic or how many transactions you wish to support per second. you define database on the basis of provisioned capacity. Instead, you just provision the throughput, i.e.
Whenever you set up DynamoDB on AWS, then you don’t allocate set amounts of disk or provision specific servers. However, we can describe how it interacts. We cannot describe what exactly the DynamoDB is as the cloud-native database architecture is proprietary closed-source. Although, there’s a development version called DynamoDB Local which is written in Java.
Each key uniquely identifies each item.Īpart from the Amazon employees, not many of us know much about the exact nature of DynamoDB. Every DynamoDB query is executed with the help of a primary key which is identified by the user. Apart from that, it also allows graphs, documents, columnar among its data model.Ī user first stores the data in DynamoDB tables and then interacts with it through PUT and GET queries which are write and read operations respectively.ĭynamoDB supports conditional operations and basic CRUD operations. The data is stored on solid-state drives which offer high I/O performance along with efficiently handling high-scale requests.ĭynamoDB uses a NoSQL database model which is nonrelational. Furthermore, it can also serve any level of request traffic. DynamoDB is known for its scalability and latencies.Īs per AWS, DynamoDB cuts cost and makes it easy to store and retrieve any amount of data. So, without any further ado, let’s begin.ĭynamoDB which is also known as Amazon Dynamo Database or DDB is a NoSQL database service provided by Amazon Web Services.
