Variables

var (
	// EnableSRVLookups controls whether the DNS resolver attempts to fetch gRPCLB
	// addresses from SRV records.  Must not be changed after init time.
	EnableSRVLookups = false

	// MinResolutionInterval is the minimum interval at which re-resolutions are
	// allowed. This helps to prevent excessive re-resolution.
	MinResolutionInterval = 30 * time.Second

	// ResolvingTimeout specifies the maximum duration for a DNS resolution request.
	// If the timeout expires before a response is received, the request will be canceled.
	//
	// It is recommended to set this value at application startup. Avoid modifying this variable
	// after initialization as it's not thread-safe for concurrent modification.
	ResolvingTimeout = 30 * time.Second
