DV-loaders provide custom Transformation steps for loading Data Vault compliant objects: Hub, Link and Satellite. These are developed using plugin extension capability offered by Pentaho Data Integration tool (PDI, aka Kettle).

With these custom Steps, you can:

• Load quickly and easily Hub, Link and Satellite
• Define as many Steps as needed inside the same Transformation
• Load mandatory attributes compliant with logical Data Vault rules
• Load non-mandatory fields as-is (ex. batch-Id for auditing)
• Adjust buffer size to fine-tune performance
