Struct mz_compute_client::protocol::command::ComputeParameters

pub struct ComputeParameters {
    pub workload_class: Option<Option<String>>,
    pub max_result_size: Option<u64>,
    pub tracing: TracingParameters,
    pub grpc_client: GrpcClientParameters,
    pub dyncfg_updates: ConfigUpdates,
}

Compute instance configuration parameters.

Parameters can be set (Some) or unset (None). Unset parameters should be interpreted to mean “use the previous value”.

Fields

workload_class: Option<Option<String>>

An optional arbitrary string that describes the class of the workload this compute instance is running (e.g., production or staging).

When Some(x), a workload_class=x label is applied to all metrics exported by the metrics registry associated with the compute instance.

max_result_size: Option<u64>

The maximum allowed size in bytes for results of peeks and subscribes.

Peeks and subscribes that would return results larger than this maximum return the respective error responses instead:

• PeekResponse::Rows is replaced by PeekResponse::Error.
• The SubscribeBatch::updates field is populated with an Err value.

tracing: TracingParameters

Tracing configuration.

grpc_client: GrpcClientParameters

gRPC client configuration.

dyncfg_updates: ConfigUpdates

Config updates for components migrated to mz_dyncfg.

Implementations

impl ComputeParameters

pub fn update(&mut self, other: ComputeParameters)

Update the parameter values with the set ones from other.

pub fn all_unset(&self) -> bool

Return whether all parameters are unset.

Trait Implementations

impl Arbitrary for ComputeParameters

type Parameters = (<Option<Option<String>> as Arbitrary>::Parameters, <Option<u64> as Arbitrary>::Parameters, <TracingParameters as Arbitrary>::Parameters, <GrpcClientParameters as Arbitrary>::Parameters, <ConfigUpdates as Arbitrary>::Parameters)

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = Map<(<Option<Option<String>> as Arbitrary>::Strategy, <Option<u64> as Arbitrary>::Strategy, <TracingParameters as Arbitrary>::Strategy, <GrpcClientParameters as Arbitrary>::Strategy, <ConfigUpdates as Arbitrary>::Strategy), fn(_: (Option<Option<String>>, Option<u64>, TracingParameters, GrpcClientParameters, ConfigUpdates)) -> ComputeParameters>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(_top: Self::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for ComputeParameters

fn clone(&self) -> ComputeParameters

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ComputeParameters

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

Formats the value using the given formatter.

impl Default for ComputeParameters

fn default() -> ComputeParameters

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ComputeParameters

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ComputeParameters

fn eq(&self, other: &ComputeParameters) -> 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.

impl RustType<ProtoComputeParameters> for ComputeParameters

fn into_proto(&self) -> ProtoComputeParameters

Convert a Self into a Proto value.

fn from_proto(proto: ProtoComputeParameters) -> Result<Self, TryFromProtoError>

Consume and convert a Proto back into a Self value.

fn into_proto_owned(self) -> Proto

A zero clone version of Self::into_proto that types can optionally implement, otherwise, the default implementation delegates to Self::into_proto.

impl Serialize for ComputeParameters

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
