Struct AttachColumnsRequest 

pub struct AttachColumnsRequest {
    pub attempt: Option<Uuid>,
    pub base: Uuid,
    pub fragment_id: Uuid,
    pub schema_changes: Option<Vec<SchemaChange>>,
    pub table: TableBinding,
}

Values for the columns that schemaChanges adds, for every row that file fragmentId of version base keeps, in stored order. The service checks their count, places them at the kept positions, writes nulls at the positions base deletes, and writes them as column files attached to the file, to prepare on an edit base of base. The file’s existing files are not rewritten. Files go under attempt’s directory.

Contract field attempt.

base: Uuid
