Functions

func New

func New(srvResolver srv.Resolver, options ...SrvResolverOptions) naming.Resolver

New creates a gRPC naming.Resolver that is backed by an SRV lookup resolver.

Types

type SrvResolverOptions

type SrvResolverOptions func(*resolver)

func WithMaximumConsecutiveErrors

func WithMaximumConsecutiveErrors(maxErr int) SrvResolverOptions

MaximumConsecutiveErrors identifies how many consecutive iterations of bad SRV Lookups to tolerate in a loop. After this limit is reached all the srv resolutions will stop. Default value is -1. -1 means there is no limit.

func WithRetryBackoff

func WithRetryBackoff(retryBackoff *backoff.Backoff) SrvResolverOptions

WithRetryBackoff sets or clears the backoff when retrying after lookup failures. By default, an exponential backoff with a maximum of MinimumRefreshInterval is used. Pass nil to clear backoff, causing instant retries.
