# ETL Pipeline Builder Skill

Builds and manages ETL (Extract, Transform, Load) pipelines for data migration, supporting incremental loads, CDC, and comprehensive monitoring.

## Purpose

Enable data pipeline creation for:
- Source-to-target mapping
- Transformation definition
- Incremental load setup
- CDC configuration
- Pipeline monitoring

## Capabilities

### 1. Source-to-Target Mapping
- Define column mappings
- Handle schema differences
- Configure data type conversions
- Manage derived columns

### 2. Transformation Definition
- Data type transformations
- Value mappings
- Aggregations
- Lookups and enrichments

### 3. Incremental Load Setup
- Define watermarks
- Configure incremental columns
- Handle deletes
- Manage merge logic

### 4. CDC Configuration
- Log-based CDC
- Trigger-based CDC
- Timestamp-based CDC
- Full load comparison

### 5. Error Handling
- Define retry policies
- Configure dead letter queues
- Handle data quality issues
- Implement alerting

### 6. Pipeline Monitoring
- Track pipeline metrics
- Monitor data volumes
- Alert on failures
- Generate SLA reports

| dbt | Transformation | CLI |
| Airbyte | Data integration | API |
| Fivetran | SaaS ETL | API |
| AWS DMS | Cloud migration | CLI |
| Debezium | CDC | Config |
