	// CertDir is the default location for mTLS certificates used by pilot.
	// Defaults to /etc/certs, matching k8s template. Can be used if you run pilot
	// as a regular user on a VM or test environment.
	CertDir = os.Getenv("PILOT_CERT_DIR")

	// MaxConcurrentStreams indicates pilot max grpc concurrent streams.
	// Default is 100k.
	MaxConcurrentStreams = os.Getenv("ISTIO_GPRC_MAXSTREAMS")

	// TraceSampling sets mesh-wide trace sampling
	// percentage, should be 0.0 - 100.0 Precision to 0.01
	// Default is 100%, not recommended for production use.
	TraceSampling = os.Getenv("PILOT_TRACE_SAMPLING")

	// PushThrottle limits the qps of the actual push. Default is 10 pushes per second.
	// On larger machines you can increase this to get faster push.
	PushThrottle = os.Getenv("PILOT_PUSH_THROTTLE")

	// PushBurst limits the burst of the actual push. Default is 100.
	PushBurst = os.Getenv("PILOT_PUSH_BURST")

	// DebugConfigs controls saving snapshots of configs for /debug/adsz.
	// Defaults to false, can be enabled with PILOT_DEBUG_ADSZ_CONFIG=1
	// For larger clusters it can increase memory use and GC - useful for small tests.
	DebugConfigs = os.Getenv("PILOT_DEBUG_ADSZ_CONFIG") == "1"

	// RefreshDuration is the duration of periodic refresh, in case events or cache invalidation fail.
	// Example: "300ms", "10s" or "2h45m".
	// Default is 0 (disabled).
	RefreshDuration = os.Getenv("V2_REFRESH")

	// DebounceAfter is the delay added to events to wait
	// after a registry/config event for debouncing.
	// This will delay the push by at least this interval, plus
	// the time getting subsequent events. If no change is
	// detected the push will happen, otherwise we'll keep
	// delaying until things settle.
	// Default is 100ms, Example: "300ms", "10s" or "2h45m".
	DebounceAfter = os.Getenv("PILOT_DEBOUNCE_AFTER")

	// DebounceMax is the maximum time to wait for events
	// while debouncing. Defaults to 10 seconds. If events keep

	// NetworkScopes isolates namespaces, limiting configuration for
	// egress and other mesh services to only hosts defined in same namespace or
