Struct ClusterPerformanceMetrics 

pub struct ClusterPerformanceMetrics {
    pub per_cluster: HashMap<i64, ClusterMetrics>,
    pub global_metrics: ClusterGlobalMetrics,
}

Cluster-specific performance metrics for V2 graph clustering.

Provides detailed metrics for individual clusters including access patterns, efficiency scores, and utilization data for optimization analysis.

Examples

use crate::backend::native::v2::wal::metrics::reporting::ClusterPerformanceMetrics;

let mut metrics = ClusterPerformanceMetrics::new();
metrics.update_cluster_stats(42, 100, 500);

Fields

per_cluster: HashMap<i64, ClusterMetrics>

Metrics per cluster ID

global_metrics: ClusterGlobalMetrics

Global cluster metrics

Implementations

impl ClusterPerformanceMetrics

pub fn new() -> Self

Create new cluster performance metrics.

Initializes empty metrics storage ready for cluster-specific performance data collection.

Returns

A new ClusterPerformanceMetrics instance

pub fn update_cluster_access(&mut self, cluster_id: i64)

Update cluster access timestamp.

Records when a cluster was last accessed, helping to identify active vs inactive clusters for optimization decisions.

Arguments

• cluster_id - ID of the cluster being accessed

pub fn update_cluster_stats( &mut self, cluster_id: i64, node_count: u32, edge_count: u64, )

Update cluster statistics with current data.

Updates comprehensive cluster metrics including node count, edge count, density, and derived efficiency scores.

Arguments

• cluster_id - ID of the cluster to update
• node_count - Current number of nodes in cluster
• edge_count - Current number of edges in cluster

pub fn reset(&mut self)

Reset cluster metrics to initial state.

Clears all cluster-specific and global metrics for fresh measurements.

pub fn get_summary(&self) -> String

Get cluster performance summary.

Returns a formatted summary of cluster performance metrics suitable for logging and monitoring dashboards.

Returns

Formatted string with cluster performance summary
