Aws Sdk Java V2 Dynamodb

This walks you through DynamoDB operations using AWS SDK for Java 2.x with the Enhanced Client, which gives you type-safe table operations instead of wrestling with raw AttributeValue maps. You'll find patterns for CRUD, queries with sort keys and GSIs, batch operations, and transactions with proper retry logic for unprocessed items. The source includes real examples of composite keys, filter expressions, and Spring Boot configuration. One thing to note: it has a sensible warning about scans consuming read capacity across your entire table, with validation steps before you use them. If you're building Java services that talk to DynamoDB and want to avoid the boilerplate of the low-level client, this covers the common patterns with actual error handling.

AWS SDK for Java 2.x - Amazon DynamoDB

Overview

Provides DynamoDB patterns using AWS SDK for Java 2.x with Enhanced Client for type-safe CRUD, queries, batch operations, transactions, and Spring Boot integration.

When to Use

CRUD operations on DynamoDB items
Querying tables with sort keys or GSI
Batch operations for multiple items
Atomic transactions across tables
Spring Boot integration with DynamoDB

Instructions

Add AWS SDK DynamoDB dependencies to pom.xml
Configure client setup (low-level or Enhanced Client)
Define entity classes with @DynamoDbBean annotations
Perform operations using DynamoDbTable (CRUD, query, scan, batch, transactions)
Handle partial failures with retry logic and exponential backoff
Use repository pattern for Spring Boot integration
