Fields

enable_adaptive: bool

Enable adaptive re-optimization

re_opt_trigger_percent: f64

Re-optimization trigger as percentage of query execution (0.0-1.0)

re_opt_trigger_seconds: u64

Re-optimization trigger in seconds

min_reopt_interval_seconds: u64

Minimum interval between re-optimizations in seconds

plan_switch_threshold: f64

Plan switch threshold (new plan must be N times better)

deviation_threshold: f64

Deviation threshold (actual/estimated ratio to trigger re-opt)

max_reoptimizations: usize

Maximum number of re-optimizations per query
