Envoy Header-To-Metadata Filter

    A typical use case for this filter is to dynamically match requests with load balancer subsets. For this, a given header’s value would be extracted and attached to the request as dynamic metadata which would then be used to match a subset of endpoints.

    A corresponding upstream cluster configuration could be:

    2.     type: EDS
    4.     lb_subset_config:
    5.       fallback_policy: ANY_ENDPOINT
    6.         - keys:
    7.             - default
    9.             - version
