Module profiler 

Performance profiler for execution statistics

This module provides Profiler for tracking per-operation and per-stratum statistics during query execution. It can be used to identify performance bottlenecks and understand resource usage patterns.

Example

use xlog_runtime::profiler::{Profiler, OpStats};

let mut profiler = Profiler::new(true);

// Record operation statistics
profiler.record(OpStats {
    op_name: "hash_join".to_string(),
    input_rows: 1000,
    output_rows: 500,
    duration_us: 1500,
    memory_bytes: 4096,
});

// Get summary
println!("{}", profiler.summary());
