type GrpcRoundTripper ¶

type GrpcRoundTripper interface {
	RoundTripGRPC(context.Context, *httpgrpc.HTTPRequest) (*httpgrpc.HTTPResponse, error)
}

GrpcRoundTripper is similar to http.RoundTripper, but works with HTTP requests converted to protobuf messages.

type Handler ¶

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

Handler accepts queries and forwards them to RoundTripper. It can log slow queries, but all other logic is inside the RoundTripper.

func NewHandler(cfg HandlerConfig, roundTripper http.RoundTripper, log log.Logger, reg prometheus.Registerer) *Handler

func (f *Handler) ServeHTTP(w http.ResponseWriter, r *http.Request)

type HandlerConfig ¶

type HandlerConfig struct {
	LogQueriesLongerThan time.Duration `yaml:"log_queries_longer_than"`
	MaxBodySize          int64         `yaml:"max_body_size"`
	QueryStatsEnabled    bool          `yaml:"query_stats_enabled"`
}

Config for a Handler.

func (cfg *HandlerConfig) RegisterFlags(f *flag.FlagSet)

type Retry ¶ added in v1.16.0

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

func NewRetry(maxRetries int, reg prometheus.Registerer) *Retry

func (r *Retry) Do(ctx context.Context, f func() (*httpgrpc.HTTPResponse, error)) (*httpgrpc.HTTPResponse, error)
