Interface PromotedColumnState

A promoted custom column plus the two facts that decide whether it may be reclaimed (U7).

interface PromotedColumnState {
    AllNullAcrossFullSync: boolean;
    ColumnName: string;
    VanishedFromSource: boolean;
}

Properties

AllNullAcrossFullSync: boolean

The column was 100% NULL across the LAST FULL sync — no synced row carried a value.

ColumnName: string

The (already-promoted) real column's name.

VanishedFromSource: boolean

The source no longer exposes this key (absent from the latest authoritative discovery / overflow).
