With CoreDNS now supporting etcdv3 as the DNS backend, we can update our federation target to etcdv3. Users will now be able to use etcdv3 server as the federation backbone. Minio will update bucket data to etcdv3 and CoreDNS can pick that data up and serve it as bucket style DNS path.

// Package base defines a balancer base that can be used to build balancers with
|
|
// different picking algorithms.
|
|
//
|
|
// The base balancer creates a new SubConn for each resolved address. The
|
|
// provided picker will only be notified about READY SubConns.
|
|
//
|
|
// This package is the base of round_robin balancer, its purpose is to be used
|
|
// to build round_robin like balancers with complex picking algorithms.
|
|
// Balancers with more complicated logic should try to implement a balancer
|
|
// builder from scratch.
|
|
//
|
|
// All APIs in this package are experimental.
