aws-sam-stock-csv-app

Minimal SAM app: S3 CSV -> Lambda -> DynamoDB

Quick start:

1. sam build
2. sam deploy --guided
3. Upload sample CSV (get bucket name from stack outputs): aws s3 cp sample_data/stock_data.csv s3:///sample_data/stock_data.csv

Local test:

1. sam local invoke "StockCsvProcessor" -e events/s3_event.json

Query DynamoDB for an item: aws dynamodb get-item --table-name --key '{"symbol":{"S":"AAPL"},"trade_date":{"S":"2025-10-10"}}'
