    },
    Rebalance,
}

Variants

Hold

No scaling action should be taken.

ScaleOut

Add nodes and backfill before quorum admission.

Fields

suggested: usize

ScaleIn

Drain listed nodes before removal.

Fields

drain: Vec<ClusterNodeId>

Nodes that can be drained by an external autoscaler.

Rebalance

Rebalance hot partitions without changing membership.

Trait Implementations

impl Clone for ScaleRecommendation

fn clone(&self) -> ScaleRecommendation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScaleRecommendation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ScaleRecommendation

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ScaleRecommendation

impl PartialEq for ScaleRecommendation

fn eq(&self, other: &ScaleRecommendation) -> 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 Serialize for ScaleRecommendation

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
