Struct AutomaticScaling

}

Automatic scaling is based on request rate, response latencies, and other application metrics.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

cool_down_period: Option<Duration>

The time period that the Autoscaler should wait before it starts collecting information from a new instance. This prevents the autoscaler from collecting information when the instance is initializing, during which the collected usage would not be reliable. Only applicable in the App Engine flexible environment.

cpu_utilization: Option<CpuUtilization>

Target scaling by CPU usage.

max_concurrent_requests: i32

Number of concurrent requests an automatic scaling instance can accept before the scheduler spawns a new instance.

Defaults to a runtime-specific value.

max_idle_instances: i32

Maximum number of idle instances that should be maintained for this version.

max_total_instances: i32

Maximum number of instances that should be started to handle requests for this version.

max_pending_latency: Option<Duration>

Maximum amount of time that a request should wait in the pending queue before starting a new instance to handle it.

min_idle_instances: i32

Minimum number of idle instances that should be maintained for this version. Only applicable for the default version of a service.

min_total_instances: i32

Minimum number of running instances that should be maintained for this version.

min_pending_latency: Option<Duration>

Minimum amount of time a request should wait in the pending queue before starting a new instance to handle it.

request_utilization: Option<RequestUtilization>

Target scaling by request utilization.

disk_utilization: Option<DiskUtilization>

Target scaling by disk usage.

network_utilization: Option<NetworkUtilization>

Target scaling by network usage.

standard_scheduler_settings: Option<StandardSchedulerSettings>

Scheduler settings for standard environment.

Trait Implementations

impl Clone for AutomaticScaling

fn clone(&self) -> AutomaticScaling

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AutomaticScaling

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for AutomaticScaling

fn default() -> AutomaticScaling

Returns the “default value” for a type.

impl Message for AutomaticScaling

fn typename() -> &'static str

The typename of this message.

impl PartialEq for AutomaticScaling

fn eq(&self, other: &AutomaticScaling) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
