Types ¶
type Benchable ¶ added in v0.15.6
type Benchable interface {
// Mark that [validatorID] has been benched on the given chain
Benched(chainID ids.ID, validatorID ids.NodeID)
// Mark that [validatorID] has been unbenched from the given chain
Unbenched(chainID ids.ID, validatorID ids.NodeID)
}
Benchable is notified when a validator is benched or unbenched from a given chain
type Benchlist ¶
type Benchlist interface {
// RegisterResponse registers the response to a query message
RegisterResponse(nodeID ids.NodeID)
// RegisterFailure registers that we didn't receive a response within the timeout
RegisterFailure(nodeID ids.NodeID)
// IsBenched returns true if messages to [validatorID]
// should not be sent over the network and should immediately fail.
IsBenched(nodeID ids.NodeID) bool
}
Therefore, nodes that consistently fail are "benched" such that queries to that node fail immediately to avoid waiting up to the full network timeout for a response.
func NewBenchlist ¶
func NewBenchlist( ctx *consensus.Context, benchable Benchable, validators validators.Manager, threshold int, minimumFailingDuration, duration time.Duration, maxPortion float64, reg prometheus.Registerer, ) (Benchlist, error)
NewBenchlist returns a new Benchlist
type Config ¶
type Config struct {
Benchable Benchable `json:"-"`
Validators validators.Manager `json:"-"`
BenchlistRegisterer metrics.MultiGatherer `json:"-"`
Threshold int `json:"threshold"`
MinimumFailingDuration time.Duration `json:"minimumFailingDuration"`
Duration time.Duration `json:"duration"`
MaxPortion float64 `json:"maxPortion"`
}
Config defines the configuration for a benchlist
type Manager ¶
type Manager interface {
// RegisterResponse registers that we receive a request response from [nodeID]
// regarding [chainID] within the timeout
RegisterResponse(chainID ids.ID, nodeID ids.NodeID)
// RegisterFailure registers that a request to [nodeID] regarding
// [chainID] timed out
RegisterFailure(chainID ids.ID, nodeID ids.NodeID)
// RegisterChain registers a new chain with metrics under [namespace]
RegisterChain(ctx *consensus.Context) error
// IsBenched returns true if messages to [nodeID] regarding chain [chainID]
// should not be sent over the network and should immediately fail.
// Returns false if such messages should be sent, or if the chain is unknown.
IsBenched(nodeID ids.NodeID, chainID ids.ID) bool
// GetBenched returns an array of chainIDs where the specified
// [nodeID] is benched. If called on an id.ShortID that does
// not map to a validator, it will return an empty array.
GetBenched(nodeID ids.NodeID) []ids.ID
}
Manager provides an interface for a benchlist to register whether queries have been successful or unsuccessful and place validators with consistently failing queries on a benchlist to prevent waiting up to the full network timeout for their responses.
func NewManager ¶
NewManager returns a manager for chain-specific query benchlisting
func NewNoBenchlist ¶ added in v0.15.6
func NewNoBenchlist() Manager
NewNoBenchlist returns an empty benchlist that will never stop any queries
