Struct TimelyConfig

pub struct TimelyConfig {
    pub workers: usize,
    pub process: usize,
    pub addresses: Vec<String>,
    pub arrangement_exert_proportionality: u32,
    pub enable_zero_copy: bool,
    pub enable_zero_copy_lgalloc: bool,
    pub zero_copy_limit: Option<usize>,
    pub enable_create_sockets_v2: bool,
}

Configuration of the cluster we will spin up

Fields

workers: usize

Number of per-process worker threads

process: usize

Identity of this process

addresses: Vec<String>

Addresses of all processes

arrangement_exert_proportionality: u32

Proportionality value that decides whether to exert additional arrangement merge effort.

Specifically, additional merge effort is exerted when the size of the second-largest batch in an arrangement is within a factor of arrangement_exert_proportionality of the size of the largest batch, or when a merge is already in progress.

The higher the proportionality value, the more eagerly arrangement batches are merged. A value of 0 (or 1) disables eager merging.

enable_zero_copy: bool

Whether to use the zero copy allocator.

enable_zero_copy_lgalloc: bool

Whether to use lgalloc to back the zero copy allocator.

zero_copy_limit: Option<usize>

Optional limit on the number of empty buffers retained by the zero copy allocator.

enable_create_sockets_v2: bool

Whether to enable the new version of create_sockets.

This flag exists to facilitate a slow rollout and is expected to be temporary.

Implementations

impl TimelyConfig

pub fn split_command(&self, parts: usize) -> Vec<Self>

Split the timely configuration into parts pieces, each with a different process number.

Trait Implementations

impl Arbitrary for TimelyConfig

type Parameters = (<usize as Arbitrary>::Parameters, <usize as Arbitrary>::Parameters, <Vec<String> as Arbitrary>::Parameters, <u32 as Arbitrary>::Parameters, <bool as Arbitrary>::Parameters, <bool as Arbitrary>::Parameters, <Option<usize> as Arbitrary>::Parameters, <bool as Arbitrary>::Parameters)

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

type Strategy = Map<(<usize as Arbitrary>::Strategy, <usize as Arbitrary>::Strategy, <Vec<String> as Arbitrary>::Strategy, <u32 as Arbitrary>::Strategy, <bool as Arbitrary>::Strategy, <bool as Arbitrary>::Strategy, <Option<usize> as Arbitrary>::Strategy, <bool as Arbitrary>::Strategy), fn(_: (usize, usize, Vec<String>, u32, bool, bool, Option<usize>, bool)) -> TimelyConfig>

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 TimelyConfig

fn clone(&self) -> TimelyConfig

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TimelyConfig

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

Formats the value using the given formatter.

impl Default for TimelyConfig

fn default() -> TimelyConfig

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TimelyConfig

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TimelyConfig

fn eq(&self, other: &TimelyConfig) -> 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<ProtoTimelyConfig> for TimelyConfig

fn into_proto(&self) -> ProtoTimelyConfig

Convert a Self into a Proto value.

fn from_proto(proto: ProtoTimelyConfig) -> 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 TimelyConfig

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
