DynamoDB - with Serverless

AUse Streams to trigger Lambda, which starts Step Functions workflows for complex processing

BUse Step Functions to replace Lambda and Streams entirely

CConfigure Lambda to write directly to Step Functions without Streams

DUse Streams only for logging and ignore Lambda and Step Functions

Step-by-Step Solution

Solution:

Step 1: Understand component roles
DynamoDB Streams detect changes, Lambda processes events, Step Functions manage workflows.
Step 2: Combine for reliability
Lambda triggered by Streams can start Step Functions for orchestrated, reliable processing.
Final Answer:
Use Streams to trigger Lambda, which starts Step Functions workflows for complex processing -> Option A
Quick Check:
Streams + Lambda + Step Functions = A [OK]

Quick Trick: Trigger Step Functions via Lambda from Streams events [OK]
