Enum ReconfigurationLifecycleV1 

pub enum ReconfigurationLifecycleV1 {
    Started,
    Finalized,
    TimedOut,
    Cancelled,
}

A transition in the lifecycle of a background cluster reconfiguration (a reconfiguration record on a managed cluster), recorded so an operator can trace a background ALTER CLUSTER from start to its resolution.

The replica creates and drops the reconfiguration induces are recorded separately, carrying CreateOrDropClusterReplicaReasonV1::Reconfiguration; this event family records the cluster-level transitions those replica lifecycle events hang off of.

Variants

Started

A reconfiguration record was written or re-targeted: the cluster is now converging onto a new target shape.

Finalized

The realized config cut over to the target and the record was cleared: a hydrated success under either ON TIMEOUT action (including one that hydrated after the deadline, since success takes precedence) or a forced ON TIMEOUT COMMIT cut-over of a not-yet-hydrated target past the deadline. The event carries the record’s deadline; comparing it to the event’s occurrence time tells an in-time cut-over from a late or forced one.

TimedOut

The deadline fired with the target not hydrated under ON TIMEOUT ROLLBACK: the record was cleared with the realized config untouched and the target replicas dropped, reverting to the pre-reconfiguration set. Emitted exactly once per timeout. The clear is durable, so the transition cannot re-fire. This event is the timeout’s papertrail; the record (and with it the abandoned target) is gone from the catalog.

Cancelled

An in-flight reconfiguration was cancelled by re-targeting the record back to the cluster’s still-realized shape (the ALTER-back cancel path); the controller drops the in-flight target replicas and clears the record.

Trait Implementations

impl Arbitrary for ReconfigurationLifecycleV1

type Parameters = ()

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

type Strategy = Union<BoxedStrategy<ReconfigurationLifecycleV1>>

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 ReconfigurationLifecycleV1

fn clone(&self) -> ReconfigurationLifecycleV1

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReconfigurationLifecycleV1

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ReconfigurationLifecycleV1

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for ReconfigurationLifecycleV1

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ReconfigurationLifecycleV1

fn cmp(&self, other: &ReconfigurationLifecycleV1) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ReconfigurationLifecycleV1

fn eq(&self, other: &ReconfigurationLifecycleV1) -> 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 PartialOrd for ReconfigurationLifecycleV1

fn partial_cmp(&self, other: &ReconfigurationLifecycleV1) -> Option<Ordering>

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

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

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

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

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

impl Serialize for ReconfigurationLifecycleV1

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
