Functions

func GetNamespace

) metrics.Scope

Types

type NamespaceCountLimitInterceptor

type NamespaceCountLimitInterceptor struct {
	sync.Mutex
	// contains filtered or unexported fields
}

func NewNamespaceCountLimitInterceptor

func NewNamespaceCountLimitInterceptor(
	namespaceRegistry namespace.Registry,
	logger log.Logger,
	countFn func(namespace string) int,
	tokens map[string]int,
) *NamespaceCountLimitInterceptor

func (*NamespaceCountLimitInterceptor) Intercept

func (ni *NamespaceCountLimitInterceptor) Intercept(
	ctx context.Context,
	req interface{},
	info *grpc.UnaryServerInfo,
	handler grpc.UnaryHandler,
) (interface{}, error)

type NamespaceIDGetter

type NamespaceIDGetter interface {
	GetNamespaceId() string
}

gRPC method request must implement either NamespaceNameGetter or NamespaceIDGetter for namespace specific metrics to be reported properly

type NamespaceLogInterceptor

type NamespaceLogInterceptor struct {
	// contains filtered or unexported fields
}

func NewNamespaceLogInterceptor

func NewNamespaceLogInterceptor(namespaceRegistry namespace.Registry, logger log.Logger) *NamespaceLogInterceptor

func (*NamespaceLogInterceptor) Intercept

func (nli *NamespaceLogInterceptor) Intercept(
	ctx context.Context,
	req interface{},
	info *grpc.UnaryServerInfo,
	handler grpc.UnaryHandler,
) (interface{}, error)

type NamespaceNameGetter

type NamespaceNameGetter interface {
	GetNamespace() string
}

gRPC method request must implement either NamespaceNameGetter or NamespaceIDGetter for namespace specific metrics to be reported properly

type NamespaceRateLimitInterceptor

type NamespaceRateLimitInterceptor struct {
	// contains filtered or unexported fields
}

func NewNamespaceRateLimitInterceptor

func NewNamespaceRateLimitInterceptor(
	namespaceRegistry namespace.Registry,
	rateLimiter quotas.RequestRateLimiter,
	tokens map[string]int,
) *NamespaceRateLimitInterceptor

func (*NamespaceRateLimitInterceptor) Intercept

func (ni *NamespaceRateLimitInterceptor) Intercept(
	ctx context.Context,
	req interface{},
	info *grpc.UnaryServerInfo,
	handler grpc.UnaryHandler,
) (interface{}, error)

type NamespaceValidatorInterceptor

type NamespaceValidatorInterceptor struct {
	// contains filtered or unexported fields
}

NamespaceValidatorInterceptor validates: 1. Namespace is specified in task token if there is a `task_token` field. 2. Namespace is specified in request if there is a `namespace` field and no `task_token` field. 3. Namespace exists. 4. Namespace from request match namespace from task token, if check is enabled with dynamic config. 5. Namespace is in correct state.

	// contains filtered or unexported fields
}

func NewRateLimitInterceptor

func NewRateLimitInterceptor(
	rateLimiter quotas.RequestRateLimiter,
	tokens map[string]int,
) *RateLimitInterceptor

func (*RateLimitInterceptor) Intercept

func (i *RateLimitInterceptor) Intercept(
	ctx context.Context,
	req interface{},
	info *grpc.UnaryServerInfo,

	metricsClient metrics.Client,
	scopes map[string]int,
	logger log.Logger,
) *TelemetryInterceptor

func (*TelemetryInterceptor) Intercept

func (ti *TelemetryInterceptor) Intercept(
	ctx context.Context,
	req interface{},
	info *grpc.UnaryServerInfo,
