Struct AnalyticWindowConfig 

pub struct AnalyticWindowConfig {
    pub functions: Vec<AnalyticFunctionConfig>,
    pub partition_columns: Vec<String>,
    pub order_columns: Vec<String>,
    pub max_partitions: usize,
}

Configuration for a streaming analytic window operator.

Fields

functions: Vec<AnalyticFunctionConfig>

Individual function configurations

partition_columns: Vec<String>

PARTITION BY columns

order_columns: Vec<String>

ORDER BY columns

max_partitions: usize

Maximum number of partitions (memory safety)

Implementations

impl AnalyticWindowConfig

pub fn from_analysis(analysis: &AnalyticWindowAnalysis) -> Self

Creates an operator configuration from an analytic window analysis.

pub fn with_max_partitions(self, max_partitions: usize) -> Self

Sets the maximum number of partitions.

pub fn has_lookahead(&self) -> bool

Returns true if any function requires lookahead buffering.

Trait Implementations

impl Clone for AnalyticWindowConfig

fn clone(&self) -> AnalyticWindowConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AnalyticWindowConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for AnalyticWindowConfig

fn eq(&self, other: &AnalyticWindowConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
