Enum gapi_grpc::google::cloud::bigquery::storage::v1beta1::ShardingStrategy

#[repr(i32)]pub enum ShardingStrategy {
    Unspecified,
    Liquid,
    Balanced,
}

Strategy for distributing data among multiple streams in a read session.

Variants

Unspecified

Same as LIQUID.

Liquid

Assigns data to each stream based on the client’s read rate. The faster the client reads from a stream, the more data is assigned to the stream. In this strategy, it’s possible to read all data from a single stream even if there are other streams present.

Balanced

Assigns data to each stream such that roughly the same number of rows can be read from each stream. Because the server-side unit for assigning data is collections of rows, the API does not guarantee that each stream will return the same number or rows. Additionally, the limits are enforced based on the number of pre-filtering rows, so some filters can lead to lopsided assignments.

Implementations

impl ShardingStrategy

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of ShardingStrategy.

pub fn from_i32(value: i32) -> Option<ShardingStrategy>

Converts an i32 to a ShardingStrategy, or None if value is not a valid variant.

Trait Implementations

impl Clone for ShardingStrategy

fn clone(&self) -> ShardingStrategy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for ShardingStrategy

impl Debug for ShardingStrategy

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

Formats the value using the given formatter.

impl Default for ShardingStrategy

fn default() -> ShardingStrategy

Returns the “default value” for a type.

impl Eq for ShardingStrategy

impl From<ShardingStrategy> for i32

fn from(value: ShardingStrategy) -> i32

Performs the conversion.

impl Hash for ShardingStrategy

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

pub fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl Ord for ShardingStrategy

fn cmp(&self, other: &ShardingStrategy) -> Ordering

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<ShardingStrategy> for ShardingStrategy

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use]pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<ShardingStrategy> for ShardingStrategy

fn partial_cmp(&self, other: &ShardingStrategy) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]pub fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]pub fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]pub fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]pub fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
