There is no update on the original PR (see below) for more then 2 weeks. So Benjamin(@ahrtr) continues to work on the PR. The first step is to rebase the PR, because there are lots of conflicts with the main branch. The change to go.mod and go.sum reverted, because they are not needed. The e2e test cases are also reverted, because they are not correct. ``` https://github.com/etcd-io/etcd/pull/14081 ``` Signed-off-by: nic-chen <chenjunxu6@gmail.com> Signed-off-by: Benjamin Wang <wachao@vmware.com>
