ELT Delta Is Derived

Enable if loading into Data Vault and the Delta has already been derived. This will provide optimized ELT loads for scenarios like streams or insert-only transaction source tables.

When enabled, the generated Satellite load treats the incoming data as the delta: the current-row comparison against the target Satellite and the row-collapse windowing are skipped, and a reduced set of load statements is generated that stages and inserts the delta directly.

When to Change This Setting

Keep the default N for regular sources, where BimlFlex derives the delta by comparing incoming rows against the current Satellite content. Enable it when the source is guaranteed to only deliver new changes — for example event streams or insert-only transaction tables — so the load skips the comparison work it does not need.
