DynamoDB with Enhanced Client - Schemas and data serialization made easy
- DynamoDB, a NoSQL Database offered by AWS, provides flexible schema, but controlling schema is important to avoid chaos.
- The AWS SDK-v2 for Java includes an EnhancedClient API for strict table schema setup and data serialization.
- The article discusses setting up the EnhancedClient API for DynamoDB local using a Spring Boot project.
- Endpoints like POST /api/v1/book, GET /api/v1/book/id, GET /api/v1/books, and GET /api/v1/books/year/{year_published} are implemented.
- A document structure for the Books table includes fields like id, author, genres, yearPublished, and more.
- Codes for setting up the EnhancedClient, Bean, and TableSchema in Java are provided for handling schema and data serialization.
- The EnhancedClient API allows fine control over the schema and robust data handling in DynamoDB.
- A service class BookService is created to power the APIs for operations like adding a book, fetching all books, and querying books by year published.
- The article showcases how EnhancedClient API simplifies data serialization and schema definition, ensuring consistency and ease of development.
- The controller in the application handles requests by delegating them to the service layer, demonstrating a clean architecture setup.
- Using EnhancedClient API streamlines data management in DynamoDB, offering a balance between data serialization control and schema flexibility.
