Struct QueryRuntimeStatistics

#[non_exhaustive]
pub struct QueryRuntimeStatistics {
    pub timeline: Option<QueryRuntimeStatisticsTimeline>,
    pub rows: Option<QueryRuntimeStatisticsRows>,
    pub output_stage: Option<QueryStage>,
}

The query execution timeline, statistics on input and output rows and bytes, and the different query stages that form the query execution plan.

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.

timeline: Option<QueryRuntimeStatisticsTimeline>

Timeline statistics such as query queue time, planning time, execution time, service processing time, and total execution time.

rows: Option<QueryRuntimeStatisticsRows>

Statistics such as input rows and bytes read by the query, rows and bytes output by the query, and the number of rows written by the query.

output_stage: Option<QueryStage>

Stage statistics such as input and output rows and bytes, execution time, and stage state. This information also includes substages and the query stage plan.

Implementations

impl QueryRuntimeStatistics

pub fn timeline(&self) -> Option<&QueryRuntimeStatisticsTimeline>

Timeline statistics such as query queue time, planning time, execution time, service processing time, and total execution time.

pub fn rows(&self) -> Option<&QueryRuntimeStatisticsRows>

Statistics such as input rows and bytes read by the query, rows and bytes output by the query, and the number of rows written by the query.

pub fn output_stage(&self) -> Option<&QueryStage>

Stage statistics such as input and output rows and bytes, execution time, and stage state. This information also includes substages and the query stage plan.

impl QueryRuntimeStatistics

pub fn builder() -> QueryRuntimeStatisticsBuilder

Creates a new builder-style object to manufacture QueryRuntimeStatistics.

Trait Implementations

impl Clone for QueryRuntimeStatistics

fn clone(&self) -> QueryRuntimeStatistics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryRuntimeStatistics

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

Formats the value using the given formatter.

impl PartialEq for QueryRuntimeStatistics

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