• Configurable.
• Data Source Agnostic. Can ingest from databases, REST API, flat files, JSON, XML etc
• Delta Load and Full Loads.
• Re-run and Retry capability.
• Audit Tracking.
• Removes the need for manual data patching.
• Data Lineage.
• One to many Level1 Transformations.
• Many to many Level2 Transformations.
• Switch on, switch off pipelines and transformations on demand.
• Extendable.
• Capability to integrate with Azure PaaS services like Diagnostic Logging.
