| * |
| * <p> |
| * It turns out there is an edge case that exists when creating sequential-ephemeral |
| * nodes. The creation can succeed on the server, but the server can crash before |
| * the created node name is returned to the client. However, the ZK session is still |
| * valid so the ephemeral node is not deleted. Thus, there is no way for the client to |
| * determine what node was created for them. |
| * </p> |
| * |
| * <p> |
| * Even without sequential-ephemeral, however, the create can succeed on the sever |
| * but the client (for various reasons) will not know it. |
| * </p> |
| * |
| * <p> |
| * Putting the create builder into protection mode works around this. |
| * The name of the node that is created is prefixed with a GUID. If node creation fails |
| * the normal retry mechanism will occur. On the retry, the parent path is first searched |
| * for a node that has the GUID in it. If that node is found, it is assumed to be the lost |
| * node that was successfully created on the first try and is returned to the caller. |
| * </p> |
