package ringhash

import "google.golang.org/grpc/internal/ringhash"

Package ringhash (internal) contains functions and types that need to be shared by the ring hash balancer and other gRPC code (such as xDS) without being exported.

Index ¶

• func SetXDSRequestHash(ctx context.Context, requestHash uint64) context.Context
• func XDSRequestHash(ctx context.Context) (uint64, bool)
• type LBConfig

Functions ¶

func SetXDSRequestHash ¶

func SetXDSRequestHash(ctx context.Context, requestHash uint64) context.Context

SetXDSRequestHash adds the request hash to the context for use in Ring Hash Load Balancing using xDS route hash_policy.

func XDSRequestHash ¶

func XDSRequestHash(ctx context.Context) (uint64, bool)

XDSRequestHash returns the request hash in the context and true if it was set from the xDS config selector. If the xDS config selector has not set the hash, it returns 0 and false.

Types ¶

type LBConfig ¶

type LBConfig struct {
	serviceconfig.LoadBalancingConfig `json:"-"`

	MinRingSize       uint64 `json:"minRingSize,omitempty"`
	MaxRingSize       uint64 `json:"maxRingSize,omitempty"`
	RequestHashHeader string `json:"requestHashHeader,omitempty"`
}

LBConfig is the balancer config for ring_hash balancer.
