Struct WindowRequest

    pub table_name: String,
    pub select: Vec<WindowSelectColumn>,
    pub windows: Vec<WindowFunctionRequest>,

Expand description

High-level window query request using semantic field names.

This is the user-facing API that uses measure names and dimension paths instead of raw SQL expressions. It gets validated and converted to WindowExecutionPlan by WindowPlanner::plan().

§Example

let request = WindowRequest {
    table_name: "tf_sales".to_string(),
    select: vec![
        WindowSelectColumn::Measure { name: "revenue".to_string(), alias: "revenue".to_string() },
        WindowSelectColumn::Dimension { path: "category".to_string(), alias: "category".to_string() },
    ],
    windows: vec![WindowFunctionRequest {
        function: WindowFunctionSpec::RunningSum { measure: "revenue".to_string() },
        alias: "running_total".to_string(),
        partition_by: vec![],
        order_by: vec![WindowOrderBy { field: "occurred_at".to_string(), direction: OrderDirection::Asc }],
        frame: Some(WindowFrame { ... }),
    }],
    where_clause: None,
    order_by: vec![],
    limit: Some(100),
    offset: None,
};

Fields§

§table_name: String

Fact table name (e.g., “tf_sales”)

§select: Vec<WindowSelectColumn>

Columns to select (measures, dimensions, filters)

§windows: Vec<WindowFunctionRequest>

Window function specifications

§where_clause: Option<WhereClause>

WHERE clause filters (applied before window computation)

§order_by: Vec<WindowOrderBy>

Final ORDER BY (after window computation)

§limit: Option<u32>

Result limit

§offset: Option<u32>

Result offset
