Struct Estimation 

#[non_exhaustive]
pub struct Estimation {
    pub cpu: Option<Cpu>,
    pub ephemeral_storage: Option<i64>,
    pub heap: Option<i64>,
    pub memory: Option<i64>,
    pub overhead: Option<i64>,
    pub additional_properties: BTreeMap<String, Value>,
    /* private fields */
}

Recommended resource values for a Spark driver or executor, derived from recent real usage metrics. Used by SPA to propose more efficient pod sizing.

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.

cpu: Option<Cpu>

CPU usage statistics derived from historical Spark job metrics. Provides multiple estimates so users can choose between conservative and cost-saving risk profiles.

ephemeral_storage: Option<i64>

Recommended ephemeral storage allocation (in MiB). Derived from job temporary storage patterns.

heap: Option<i64>

Recommended JVM heap size (in MiB).

memory: Option<i64>

Recommended total memory allocation (in MiB). Includes both heap and overhead.

overhead: Option<i64>

Recommended JVM overhead (in MiB). Computed as total memory - heap.

additional_properties: BTreeMap<String, Value>

Implementations

impl Estimation

pub fn new() -> Estimation

pub fn cpu(self, value: Cpu) -> Self

pub fn ephemeral_storage(self, value: i64) -> Self

pub fn heap(self, value: i64) -> Self

pub fn memory(self, value: i64) -> Self

pub fn overhead(self, value: i64) -> Self

pub fn additional_properties(self, value: BTreeMap<String, Value>) -> Self

Trait Implementations

impl Clone for Estimation

fn clone(&self) -> Estimation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Estimation

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

Formats the value using the given formatter.

impl Default for Estimation

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Estimation

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Estimation

fn eq(&self, other: &Estimation) -> 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 Estimation

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
