What is the status of incremental xDS support? ============================================== The :ref:`incremental xDS ` protocol is designed to improve efficiency, scalability and functional use of xDS updates via two mechanisms: * Delta xDS. Resource deltas are delivered rather than state-of-the-world. * On-demand xDS. Resource can be lazy loaded depending on request contents. Currently, all xDS protocols (including ADS) support delta xDS. On-demand xDS is supported for :ref:`VHDS ` only.
