type DnsCacheConfig Uses

type DnsCacheConfig struct {

    // The name of the cache. Multiple named caches allow independent dynamic forward proxy
    // configurations to operate within a single Envoy process using different configurations. All
    // configurations with the same name *must* otherwise have the same settings when referenced
    // from different configuration components. Configuration will fail to load if this is not
    // the case.
    Name string `protobuf:"bytes,1,opt,name=name,proto3" json:"name,omitempty"`
    // The DNS lookup family to use during resolution.
    // [#comment:TODO(mattklein123): Figure out how to support IPv4/IPv6 "happy eyeballs" mode. The
    // way this might work is a new lookup family which returns both IPv4 and IPv6 addresses, and
    // then configures a host to have a primary and fall back address. With this, we could very
    // likely build a "happy eyeballs" connection pool which would race the primary / fall back
    // address and return the one that wins. This same method could potentially also be used for
    // QUIC to TCP fall back.]
    DnsLookupFamily v2.Cluster_DnsLookupFamily `protobuf:"varint,2,opt,name=dns_lookup_family,json=dnsLookupFamily,proto3,enum=envoy.api.v2.Cluster_DnsLookupFamily" json:"dns_lookup_family,omitempty"`
    // The DNS refresh rate for currently cached DNS hosts. If not specified defaults to 60s.
    // .. note:
    //  The returned DNS TTL is not currently used to alter the refresh rate. This feature will be
    //  added in a future change.
    // .. note:
    // The refresh rate is rounded to the closest millisecond, and must be at least 1ms.
    DnsRefreshRate *duration.Duration `protobuf:"bytes,3,opt,name=dns_refresh_rate,json=dnsRefreshRate,proto3" json:"dns_refresh_rate,omitempty"`
    // The TTL for hosts that are unused. Hosts that have not been used in the configured time
    // interval will be purged. If not specified defaults to 5m.
    // .. note:
    //   The TTL is only checked at the time of DNS refresh, as specified by *dns_refresh_rate*. This
    //   means that if the configured TTL is shorter than the refresh rate the host may not be removed
    //   immediately.
    //  .. note:
    //   The TTL has no relation to DNS TTL and is only used to control Envoy's resource usage.
    HostTtl *duration.Duration `protobuf:"bytes,4,opt,name=host_ttl,json=hostTtl,proto3" json:"host_ttl,omitempty"`
    // The maximum number of hosts that the cache will hold. If not specified defaults to 1024.
    // .. note:
    //   The implementation is approximate and enforced independently on each worker thread, thus
    //   it is possible for the maximum hosts in the cache to go slightly above the configured
    //   value depending on timing. This is similar to how other circuit breakers work.
    MaxHosts *wrappers.UInt32Value `protobuf:"bytes,5,opt,name=max_hosts,json=maxHosts,proto3" json:"max_hosts,omitempty"`
    // If the DNS failure refresh rate is specified,
    // this is used as the cache's DNS refresh rate when DNS requests are failing. If this setting is
    // not specified, the failure refresh rate defaults to the dns_refresh_rate.
