public static final class Metadata.Builder extends com.google.protobuf.GeneratedMessage.Builder<Metadata.Builder> implements MetadataOrBuilder
 Metadata provides additional inputs to filters based on matched listeners,
 filter chains, routes and endpoints. It is structured as a map, usually from
 filter name (in reverse DNS format) to metadata specific to the filter. Metadata
 key-values for a filter are merged as connection and request handling occurs,
 with later values for the same key overriding earlier values.

 An example use of metadata is providing additional values to
 http_connection_manager in the envoy.http_connection_manager.access_log
 namespace.

 Another example use of metadata is to per service config info in cluster metadata, which may get
 consumed by multiple filters.

 For load balancing, Metadata provides a means to subset cluster endpoints.
 Endpoints have a Metadata object associated and routes contain a Metadata
 object to match against. There are some well defined metadata used today for
 this purpose:

 * ``{"envoy.lb": {"canary": <bool> }}`` This indicates the canary status of an
 endpoint and is also used during header processing
 (x-envoy-upstream-canary) and for stats purposes.
