Package-Level Type Names (total 3, all are exported)
/* sort exporteds by: | */
ClientParameters is used to set keepalive parameters on the client-side. These configure how the client will actively probe to notice when a connection is broken and send pings so intermediaries will be aware of the liveness of the connection. Make sure these parameters are set in coordination with the keepalive policy on the server, as incompatible settings can result in closing of connection. If true, client sends keepalive pings even with no active RPCs. If false, when there are no active RPCs, Time and Timeout will be ignored and no keepalive pings will be sent. // false by default. After a duration of this time if the client doesn't see any activity it pings the server to see if the transport is still alive. If set below 10s, a minimum value of 10s will be used instead. // The current default value is infinity. After having pinged for keepalive check, the client waits for a duration of Timeout and if no activity is seen even after that the connection is closed. // The current default value is 20 seconds. func google.golang.org/grpc.WithKeepaliveParams(kp ClientParameters) grpc.DialOption
EnforcementPolicy is used to set keepalive enforcement policy on the server-side. Server will close connection with a client that violates this policy. MinTime is the minimum amount of time a client should wait before sending a keepalive ping. // The current default value is 5 minutes. If true, server allows keepalive pings even when there are no active streams(RPCs). If false, and client sends ping when there are no active streams, server will send GOAWAY and close the connection. // false by default. func google.golang.org/grpc.KeepaliveEnforcementPolicy(kep EnforcementPolicy) grpc.ServerOption
ServerParameters is used to set keepalive and max-age parameters on the server-side. MaxConnectionAge is a duration for the maximum amount of time a connection may exist before it will be closed by sending a GoAway. A random jitter of +/-10% will be added to MaxConnectionAge to spread out connection storms. // The current default value is infinity. MaxConnectionAgeGrace is an additive period after MaxConnectionAge after which the connection will be forcibly closed. // The current default value is infinity. MaxConnectionIdle is a duration for the amount of time after which an idle connection would be closed by sending a GoAway. Idleness duration is defined since the most recent time the number of outstanding RPCs became zero or the connection establishment. // The current default value is infinity. After a duration of this time if the server doesn't see any activity it pings the client to see if the transport is still alive. If set below 1s, a minimum value of 1s will be used instead. // The current default value is 2 hours. After having pinged for keepalive check, the server waits for a duration of Timeout and if no activity is seen even after that the connection is closed. // The current default value is 20 seconds. func google.golang.org/grpc.KeepaliveParams(kp ServerParameters) grpc.ServerOption
