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
