Overview
This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.
Periodically retrieves SRV records for the cluster’s SRV URI, and sets the cluster’s server list to the SRV lookup result.
If an error is encountered during SRV lookup or an SRV record is invalid or disallowed for security reasons, a warning is logged and monitoring continues.
