+# Event-Driven Data Pipeline with Lambda Durable Functions
+
+This serverless pattern demonstrates how to build an event-driven data processing pipeline using AWS Lambda Durable Functions with **direct SQS Event Source Mapping** and Lambda invoke chaining.
+
+## How It Works
+
+This pattern demonstrates an event-driven data processing pipeline using AWS Lambda Durable Functions with direct SQS Event Source Mapping. When a message arrives in the SQS queue, it directly triggers the durable function (no intermediary Lambda needed). The durable function then orchestrates a series of specialized processing steps using Lambda invoke chaining - first validating the incoming data, then transforming it (converting data_source to uppercase), and finally storing the processed results in DynamoDB. Throughout this process, the durable function automatically creates checkpoints, enabling fault-tolerant execution that can recover from failures without losing progress. The entire pipeline operates within the 15-minute ESM execution limit, making it ideal for reliable batch processing workflows.
+
+## Architecture Overview
+
+The pattern showcases two key Durable Functions capabilities:
+1. **Direct Event Source Mapping**: SQS directly triggers the durable function (15-minute limit)
+2. **Lambda Invoke Chaining**: Orchestrates specialized processing functions
+
+![Architecture Diagram](architecture-diagram.png)
+
+## Key Features
+
+- **Direct ESM Integration**: No intermediary function needed
+- **15-minute execution constraint**: Demonstrates ESM time limits
+- **Fault-tolerant processing**: Automatic checkpointing and recovery
+- **Microservices coordination**: Chains specialized Lambda functions
+- **Batch processing**: Handles multiple SQS records per invocation
+- **Simple storage**: Uses DynamoDB for processed data
+
+## Important ESM Constraints
+
+⚠️ **15-Minute Execution Limit**: When using Event Source Mapping with Durable Functions, the total execution time cannot exceed 15 minutes. This includes:
+- All processing steps
+- Function invocations
+- No long wait operations
+
+## Use Cases
+
+- ETL pipelines with validation and transformation
+- Event-driven microservices orchestration
+- Batch processing with fault tolerance
+- Data processing workflows requiring checkpointing
+
+## Prerequisites
+
+- [AWS CLI](https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html) configured with appropriate permissions
+- [AWS SAM CLI](https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/install-sam-cli.html) latest version installed
+- [Python 3.14](https://www.python.org/downloads/release/python-3140/) runtime installed
+
+## Deployment
+
+1. **Build the application**:
+   ```bash
+   sam build
+   ```
+
+2. **Deploy to AWS**:
+   ```bash
+   sam deploy --guided
+   ```
+   
+   Note the outputs after deployment:
+   - `DataProcessingQueueUrl`: Use this for `<QUEUE_URL>`
+   - `ProcessedDataTable`: Use this for `<PROCESSED_DATA_TABLE>`
+
+3. **Test the pipeline**:
+   ```bash
+   # Send a test message to SQS
+   aws sqs send-message \
+     --queue-url <QUEUE_URL> \
+     --message-body '{"data_source": "test.csv", "processing_type": "standard"}'
+   ```
+
+4. **Verify successful processing**:
+   ```bash
+   # Check if data was processed and stored in DynamoDB
+   aws dynamodb scan --table-name <PROCESSED_DATA_TABLE> --query 'Items[*]'
+   ```
+   
+   **Success indicators:**
+   - You should see at least one item in the DynamoDB table
+   - Original input data: `"data_source": "test.csv"`
+   - Transformed data: `"data_source": "TEST.CSV"` (uppercase transformation applied)
+   - Execution tracking with unique `execution_id`
+   - Timestamps showing when data was processed and stored
+   
+   This confirms the entire pipeline worked: SQS → Durable Function → Validation → Transformation → Storage → DynamoDB
+
+## Components
+
+### 1. Durable Pipeline Function (`src/durable_pipeline/`)
+- **Direct SQS Event Source Mapping**: Receives SQS events directly
+- **15-minute execution limit**: Must complete all processing within ESM constraints
+- **Batch processing**: Handles multiple SQS records per invocation
+- **Lambda invoke chaining**: Orchestrates validation, transformation, and storage
+- **Automatic checkpointing**: Recovers from failures without losing progress
+
+### 2. Specialized Processing Functions
+- **Validation Function**: Simple data validation checks
+- **Transformation Function**: Basic data transformation
+- **Storage Function**: Persists processed data to DynamoDB
+
+## Monitoring
+
+- CloudWatch Logs for execution tracking
+- DynamoDB table for processed data
+- SQS DLQ for failed messages
+
+## Configuration
+
+Key environment variables:
+- `ENVIRONMENT`: Deployment environment (dev/prod)
+- `PROCESSED_DATA_TABLE`: DynamoDB table for processed data
+- `VALIDATION_FUNCTION_ARN`: ARN of validation function
+- `TRANSFORMATION_FUNCTION_ARN`: ARN of transformation function
+- `STORAGE_FUNCTION_ARN`: ARN of storage function
+
+## ESM-Specific Considerations
+
+- **Execution Timeout**: Set to 900 seconds (15 minutes) maximum
+- **Batch Size**: Configured for optimal processing (5 records)
+- **Error Handling**: Uses SQS DLQ for failed batches
+- **Efficient Processing**: Optimized for speed to stay within time limits
+
+## Error Handling
+
+- Automatic retries with exponential backoff
+- Dead Letter Queue for failed messages
+- Partial batch failure support
+- Checkpoint-based recovery
+
+## Cost Optimization
+
+- Pay only for active compute time
+- Efficient batch processing
+- Automatic scaling based on queue depth
+
+## Cleanup
+
+```bash
+sam delete
+```
