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.
