# Kessoku Automation Workflow for Data Processing

## Workflow Overview
- **Source**: CSV files from S3 bucket
- **Processing**: Data cleaning and transformation
- **Target**: PostgreSQL database
- **Dependencies**: Parallel processing of 5 CSV files

## Step-by-Step Guide

### 1. Set Up Kessoku
```go
import (
    "github.com/tsenart/kessoku"
    "github.com/tsenart/kessoku/parallel"
)

func main() {
    // Initialize Kessoku
    k := kessoku.New()
    // ...
}
```

### 2. Define Data Processing Function
```go
func processData(data []byte) ([]byte, error) {
    // Data cleaning and transformation logic
    // ...
    return transformedData, nil
}
```

### 3. Set Up Parallel Dependencies
```go
k.Go(parallel.New(5, func(ctx context.Context, i int) error {
    // Process each CSV file in parallel
    // ...
    return nil
}))
```

### 4. Execute Workflow
```go
if err := k.Wait(); err != nil {
    log.Fatal(err)
}
```

## Expected Output
- Cleaned and transformed data successfully injected into PostgreSQL
- Parallel processing completed in [TIME] seconds
- Error handling and logging implemented
