Struct GraphWindowFunctions

Source

pub struct GraphWindowFunctions;

Expand description

Placeholder for window functions - will implement proper DataFusion window functions when we have the core SQL functionality working

Implementations§

Source §

impl GraphWindowFunctions

Source

pub fn new() -> Self

Source

pub fn pagerank_window( &self, _partition_values: &[f64], ) -> DataFusionResult<f64>

Future implementation of PageRank window function Will support: SELECT node_id, pagerank() OVER (PARTITION BY component) FROM nodes

Source

pub fn degree_centrality_window( &self, _partition_values: &[u64], ) -> DataFusionResult<f64>

Future implementation of degree centrality window function Will support: SELECT node_id, degree_centrality() OVER (PARTITION BY component) FROM nodes

Source

pub fn betweenness_centrality_window( &self, _partition_values: &[f64], ) -> DataFusionResult<f64>

Future implementation of betweenness centrality window function Will support: SELECT node_id, betweenness_centrality() OVER (PARTITION BY component) FROM nodes
