Implement efficient search strategies that minimize computational overhead through proper ordering, early termination, and targeted scope reduction. This involves three key principles:
Strategic Ordering: Prioritize search candidates to increase likelihood of early success. For example, when allocating devices, place simpler options (without binding conditions) before complex ones to reduce allocation failures and retries.
Early Termination: Add explicit break statements or return conditions once the desired result is found, avoiding unnecessary iterations through remaining candidates.
Scope Reduction: Target searches to specific subsets rather than iterating through entire collections when the context allows for narrower scope.
Example of optimized device search with early termination:
// Before: searching all devices unnecessarily
for _, device := range slice.Spec.Devices {
if device.Name == internal.id.Device && len(device.Basic.BindingConditions) > 0 {
allocationResult.Devices.Results[i].BindingConditions = device.Basic.BindingConditions
// continues searching even after match found
}
}
// After: early termination once target found
for _, device := range slice.Spec.Devices {
if device.Name == internal.id.Device {
allocationResult.Devices.Results[i].BindingConditions = device.Basic.BindingConditions
break // stop searching once found
}
}
Consider implementing tiered allocation approaches where multiple fallback strategies are attempted in order of preference, allowing the algorithm to gracefully degrade while maintaining optimal performance for common cases.
