// [#protodoc-title: Aggregated Discovery Service (ADS)]

// [#not-implemented-hide:] Discovery services for endpoints, clusters, routes,
// and listeners are retained in the package `envoy.api.v2` for backwards
// compatibility with existing management servers. New development in discovery
// services should proceed in the package `envoy.service.discovery.v2`.

// See https://github.com/lyft/envoy-api#apis for a description of the role of
// ADS and how it is intended to be used by a management server. ADS requests
// have the same structure as their singleton xDS counterparts, but can
// multiplex many resource types on a single stream. The type_url in the
// DiscoveryRequest/DiscoveryResponse provides sufficient information to recover
// the multiplexed singleton APIs at the Envoy instance and management server.

// [#not-implemented-hide:] Not configuration. Workaround c++ protobuf issue with importing
