DynamoDB

Amazon DynamoDB is a fast, fully managed NoSQL database service that provides a highly available and scalable way to store and retrieve large amounts of data.

You can create a table in DynamoDB by using the AWS Management Console, the AWS CLI, or the DynamoDB API. You will need to specify the table name, primary key, and attributes for your table.

A primary key in DynamoDB is an attribute that uniquely identifies each item in a table. It can be either a single attribute or a composite of two attributes (known as a partition key and sort key).

You can insert data into a DynamoDB table by using the AWS Management Console, the AWS CLI, or the DynamoDB API. You will need to specify the table name, primary key, and attributes for each item you want to insert.

DynamoDB Auto Scaling automatically scales your read and write capacity as needed to handle changes in traffic or other usage patterns. This helps ensure that your application has the resources it needs to run smoothly, even during peak periods.

You can optimize your DynamoDB table for performance by following best practices such as choosing the right data type and attribute name, using indexes and views, and configuring capacity settings to meet your application's needs.

DynamoDB is a NoSQL database that stores data in a key-value or document-based format. Relational databases like MySQL store data in tables with well-defined schemas. DynamoDB provides a flexible schema that can be modified at runtime, while relational databases require a predefined schema.
