Functions ¶
func ClientInterceptorOptions ¶ added in v1.2.0
func ClientInterceptorOptions(stream []grpc.StreamClientInterceptor, unary []grpc.UnaryClientInterceptor) []option.ClientOption
ClientInterceptorOptions returns client options to use for the client's gRPC connection, using the given streaming and unary RPC interceptors.
The passed interceptors are applied after internal interceptors which inject Google client information into the gRPC context.
func DefaultClientOptions ¶
func DefaultClientOptions(endpoint, mtlsEndpoint, scope, userAgent string) ([]option.ClientOption, error)
DefaultClientOptions returns the default client options to use for the client's gRPC connection.
func EnableBigtableConnectionPool ¶ added in v1.41.0
func EnableBigtableConnectionPool() bool
EnableBigtableConnectionPool uses new conn pool if envVar is set.
Types ¶
type LoadBalancingStrategy ¶ added in v1.41.0
type LoadBalancingStrategy int
LoadBalancingStrategy for connection pool.
const ( // RoundRobin is the round_robin gRPC load balancing policy. RoundRobin LoadBalancingStrategy = iota // LeastInFlight is the least_in_flight gRPC load balancing policy (custom). LeastInFlight // PowerOfTwoLeastInFlight is the power_of_two_least_in_flight gRPC load balancing policy (custom). PowerOfTwoLeastInFlight )
func BigtableLoadBalancingStrategy ¶ added in v1.41.0
func BigtableLoadBalancingStrategy() LoadBalancingStrategy
BigtableLoadBalancingStrategy returns the gRPC service config JSON string for the chosen policy.
func (LoadBalancingStrategy) String ¶ added in v1.41.0
func (s LoadBalancingStrategy) String() string
String returns the string representation of the LoadBalancingStrategy.
