Constants

const (
	// ResourceCPU CPU, in cores. (500m = .5 cores)
	ResourceCPU = "cpu"
	// ResourceMemory Memory, in bytes. (500Gi = 500GiB = 500 * 1024 * 1024 * 1024)
	ResourceMemory = "memory"
	// ResourceStorage Volume size, in bytes (e,g. 5Gi = 5GiB = 5 * 1024 * 1024 * 1024)
	ResourceStorage = "storage"
)

const (
	// DefaultMilliCPURequest defines default milli cpu request number.
	DefaultMilliCPURequest int64 = 100 // 0.1 core
	// DefaultMemoryRequest defines default memory request size.
	DefaultMemoryRequest int64 = 200 * 1024 * 1024 // 200 MB
)

const (
	// DefaultCPUWeight defines default cpu weight (allowed weights go from 1 to 100)
	DefaultCPUWeight int64 = 1
	// DefaultMemoryWeight defines default memory weight (allowed weights go from 1 to 100)
	DefaultMemoryWeight int64 = 1
	// DefaultStorageWeight defines default storage weight (allowed weights go from 1 to 100)
	DefaultStorageWeight int64 = 1
)

Resources to consider when scoring. The default resource set includes "cpu" and "memory" with an equal weight.

const (
	// MaxNodeScore is the maximum score a Score plugin is expected to return.
	MaxNodeScore int64 = 100

	// MinNodeScore is the minimum score a Score plugin is expected to return.
	MinNodeScore int64 = 0

	// MaxTotalScore is the maximum total score.
	MaxTotalScore int64 = math.MaxInt64
