Metrics from Optimize

Fields

num_files_added: u64

Number of optimized files added

num_files_removed: u64

Number of unoptimized files removed

files_added: MetricDetails

Detailed metrics for the add operation

files_removed: MetricDetails

Detailed metrics for the remove operation

partitions_optimized: u64

Number of partitions that had at least one file optimized

num_batches: u64

The number of batches written

total_considered_files: usize

How many files were considered during optimization. Not every file considered is optimized

total_files_skipped: usize

How many files were considered for optimization but were skipped

preserve_insertion_order: bool

The order of records from source files is preserved

Implementations

impl Metrics

pub fn add(&mut self, partial: &PartialMetrics)

Add a partial metric to the metrics

Trait Implementations

impl Clone for Metrics

fn clone(&self) -> Metrics

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Metrics

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

Formats the value using the given formatter.

impl Default for Metrics

fn default() -> Metrics

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Metrics

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Metrics

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
