    • getTransportSocketMatchesList

      public List<Cluster.TransportSocketMatch> getTransportSocketMatchesList()
       Configuration to use different transport sockets for different endpoints.  The entry of
 ``envoy.transport_socket_match`` in the :ref:`LbEndpoint.Metadata
 <envoy_v3_api_field_config.endpoint.v3.LbEndpoint.metadata>` is used to match against the
 transport sockets as they appear in the list. If a match is not found, the search continues in
 :ref:`LocalityLbEndpoints.Metadata
 <envoy_v3_api_field_config.endpoint.v3.LocalityLbEndpoints.metadata>`.  The first :ref:`match
 <envoy_v3_api_msg_config.cluster.v3.Cluster.TransportSocketMatch>` is used.  For example, with
 the following match

 .. code-block:: yaml

 transport_socket_matches:
 - name: "enableMTLS"
 match:
 acceptMTLS: true
 transport_socket:
 name: envoy.transport_sockets.tls
 config: { ... } # tls socket configuration
 - name: "defaultToPlaintext"
 match: {}
 transport_socket:
 name: envoy.transport_sockets.raw_buffer

 Connections to the endpoints whose metadata value under ``envoy.transport_socket_match``
 having "acceptMTLS"/"true" key/value pair use the "enableMTLS" socket configuration.

 If a :ref:`socket match <envoy_v3_api_msg_config.cluster.v3.Cluster.TransportSocketMatch>` with empty match
 criteria is provided, that always match any endpoint. For example, the "defaultToPlaintext"
 socket match in case above.

 If an endpoint metadata's value under ``envoy.transport_socket_match`` does not match any
 ``TransportSocketMatch``, the locality metadata is then checked for a match. Barring any
 matches in the endpoint or locality metadata, the socket configuration fallbacks to use the
 ``tls_context`` or ``transport_socket`` specified in this cluster.

 This field allows gradual and flexible transport socket configuration changes.

 The metadata of endpoints in EDS can indicate transport socket capabilities. For example,
 an endpoint's metadata can have two key value pairs as "acceptMTLS": "true",
 "acceptPlaintext": "true". While some other endpoints, only accepting plaintext traffic
 has "acceptPlaintext": "true" metadata information.

 Then the xDS server can configure the CDS to a client, Envoy A, to send mutual TLS
 traffic for endpoints with "acceptMTLS": "true", by adding a corresponding
 ``TransportSocketMatch`` in this field. Other client Envoys receive CDS without
 ``transport_socket_match`` set, and still send plain text traffic to the same cluster.

 This field can be used to specify custom transport socket configurations for health
 checks by adding matching key/value pairs in a health check's
 :ref:`transport socket match criteria <envoy_v3_api_field_config.core.v3.HealthCheck.transport_socket_match_criteria>` field.

 socket match in case above.

 If an endpoint metadata's value under ``envoy.transport_socket_match`` does not match any
 ``TransportSocketMatch``, the locality metadata is then checked for a match. Barring any
 matches in the endpoint or locality metadata, the socket configuration fallbacks to use the
 ``tls_context`` or ``transport_socket`` specified in this cluster.

 This field allows gradual and flexible transport socket configuration changes.

 The metadata of endpoints in EDS can indicate transport socket capabilities. For example,
 an endpoint's metadata can have two key value pairs as "acceptMTLS": "true",
 "acceptPlaintext": "true". While some other endpoints, only accepting plaintext traffic
 has "acceptPlaintext": "true" metadata information.

 Then the xDS server can configure the CDS to a client, Envoy A, to send mutual TLS
 traffic for endpoints with "acceptMTLS": "true", by adding a corresponding
 ``TransportSocketMatch`` in this field. Other client Envoys receive CDS without
 ``transport_socket_match`` set, and still send plain text traffic to the same cluster.

 This field can be used to specify custom transport socket configurations for health
 checks by adding matching key/value pairs in a health check's
 :ref:`transport socket match criteria <envoy_v3_api_field_config.core.v3.HealthCheck.transport_socket_match_criteria>` field.

      public boolean getCloseConnectionsOnHostHealthFailure()
       If an upstream host becomes unhealthy (as determined by the configured health checks
 or outlier detection), immediately close all connections to the failed host.

 .. note::

 This is currently only supported for connections created by tcp_proxy.

 .. note::

 The current implementation of this feature closes all connections immediately when
 the unhealthy status is detected. If there are a large number of connections open
 to an upstream host that becomes unhealthy, Envoy may spend a substantial amount of
 time exclusively closing these connections, and not processing any other traffic.

    • hasUpstreamConfig

      public boolean hasUpstreamConfig()
       Optional customization and configuration of upstream connection pool, and upstream type.

 Currently this field only applies for HTTP traffic but is designed for eventual use for custom
 TCP upstreams.

 For HTTP traffic, Envoy will generally take downstream HTTP and send it upstream as upstream
 HTTP, using the http connection pool and the codec from ``http2_protocol_options``

 For routes where CONNECT termination is configured, Envoy will take downstream CONNECT
 requests and forward the CONNECT payload upstream over raw TCP using the tcp connection pool.

 The default pool used is the generic connection pool which creates the HTTP upstream for most
 HTTP requests, and the TCP upstream if CONNECT termination is configured.

 If users desire custom connection pool or upstream behavior, for example terminating
 CONNECT only if a custom filter indicates it is appropriate, the custom factories
 can be registered and configured here.
