Types ¶
type Client ¶
type Client struct { Conn *zk.Conn // During the initial listing of the /d2/uris node for a new cluster, this duration specifies how long to for the // first host to show up. If the /d2/services node exists for a service, it is impossible to know whether or not a // host will ever show up in the /d2/uris node for that service, which is why this timeout is provided. // A positive value will be used as-is, a 0 value will default to DefaultInitialUriWatchTimeout and a negative value // disables the timeout altogether InitialZkWatchTimeout time.Duration // contains filtered or unexported fields }
func (*Client) ResolveHostnameAndContextForQuery ¶ added in v1.0.3
func (*Client) SingleServiceClient ¶ added in v1.0.3
func (c *Client) SingleServiceClient(serviceName string) *SingleServiceClient
SingleServiceClient will always return URIs from the given serviceName instead of getting them from the service specified in resourceBaseName in ResolveHostnameAndContextForQuery. Some services announce to special D2 cluster instead of the resource name (i.e. by default, the service name is equal to the resource name).
type Cluster ¶ added in v0.1.1
type Cluster struct { ClusterName string `json:"clusterName"` PartitionProperties struct { HashAlgorithm string `json:"hashAlgorithm"` PartitionCount int `json:"partitionCount"` PartitionKeyRegex string `json:"partitionKeyRegex"` PartitionType string `json:"partitionType"` } `json:"partitionProperties"` }
type SingleServiceClient ¶ added in v0.4.0
type SingleServiceClient struct {
// contains filtered or unexported fields
}
func (*SingleServiceClient) ResolveHostnameAndContextForQuery ¶ added in v0.7.3
type Uri ¶
type Uri struct { Weights map[url.URL]float64 Properties map[url.URL]UriProperty PartitionDesc map[url.URL]map[int]float64 }
func (*Uri) UnmarshalJSON ¶
