Struct MultiClusterRoutingUseAny 

#[non_exhaustive]
pub struct MultiClusterRoutingUseAny {
    pub cluster_ids: Vec<String>,
    pub affinity: Option<Affinity>,
    /* private fields */
}

Read/write requests are routed to the nearest cluster in the instance, and will fail over to the nearest cluster that is available in the event of transient errors or delays. Clusters in a region are considered equidistant. Choosing this option sacrifices read-your-writes consistency to improve availability.

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.

cluster_ids: Vec<String>

The set of clusters to route to. The order is ignored; clusters will be tried in order of distance. If left empty, all clusters are eligible.

affinity: Option<Affinity>

Possible algorithms for routing affinity. If enabled, Bigtable will route between equidistant clusters in a deterministic order rather than choosing randomly.

This mechanism gives read-your-writes consistency for most requests under most circumstances, without sacrificing availability. Consistency is not guaranteed, as requests might still fail over between clusters in the event of errors or latency.

Implementations

impl MultiClusterRoutingUseAny

pub fn new() -> Self

pub fn set_cluster_ids<T, V>(self, v: T) -> Self

where T: IntoIterator<Item = V>, V: Into<String>,

Sets the value of cluster_ids.

Example

let x = MultiClusterRoutingUseAny::new().set_cluster_ids(["a", "b", "c"]);

pub fn set_affinity<T: Into<Option<Affinity>>>(self, v: T) -> Self

Sets the value of affinity.

Note that all the setters affecting affinity are mutually exclusive.

Example

use google_cloud_bigtable_admin_v2::model::app_profile::multi_cluster_routing_use_any::RowAffinity;
let x = MultiClusterRoutingUseAny::new().set_affinity(Some(
    google_cloud_bigtable_admin_v2::model::app_profile::multi_cluster_routing_use_any::Affinity::RowAffinity(RowAffinity::default().into())));

pub fn row_affinity(&self) -> Option<&Box<RowAffinity>>

The value of affinity if it holds a RowAffinity, None if the field is not set or holds a different branch.

pub fn set_row_affinity<T: Into<Box<RowAffinity>>>(self, v: T) -> Self

Sets the value of affinity to hold a RowAffinity.

Note that all the setters affecting affinity are mutually exclusive.

Example

use google_cloud_bigtable_admin_v2::model::app_profile::multi_cluster_routing_use_any::RowAffinity;
let x = MultiClusterRoutingUseAny::new().set_row_affinity(RowAffinity::default()/* use setters */);
assert!(x.row_affinity().is_some());

Trait Implementations

impl Clone for MultiClusterRoutingUseAny

fn clone(&self) -> MultiClusterRoutingUseAny

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MultiClusterRoutingUseAny

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

Formats the value using the given formatter.

impl Default for MultiClusterRoutingUseAny

fn default() -> MultiClusterRoutingUseAny

Returns the “default value” for a type.

impl Message for MultiClusterRoutingUseAny

fn typename() -> &'static str

The typename of this message.

impl PartialEq for MultiClusterRoutingUseAny

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