Struct TableChangeInsight 

#[non_exhaustive]
pub struct TableChangeInsight {
    pub table_reference: Option<TableReference>,
    pub metadata_cache_staleness_insight: Option<MetadataCacheStalenessInsight>,
    pub metadata_cache_not_used_but_used_previously: Option<bool>,
    /* private fields */
}

Table-level performance insights compared to previous runs. These insights don’t apply to specific query stages, rather they apply to the whole table.

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.

table_reference: Option<TableReference>

Output only. The table that was queried.

metadata_cache_staleness_insight: Option<MetadataCacheStalenessInsight>

Output only. If present, indicates that the table’s metadata column index staleness has increased significantly compared to previous jobs with the same query hash.

metadata_cache_not_used_but_used_previously: Option<bool>

Output only. True if the table’s column metadata index was not used in the current job, but was used in a previous job with the same query hash.

Implementations

impl TableChangeInsight

pub fn new() -> Self

Creates a new default instance.

pub fn set_table_reference<T>(self, v: T) -> Self

where T: Into<TableReference>,

Sets the value of table_reference.

Example

use google_cloud_bigquery_v2::model::TableReference;
let x = TableChangeInsight::new().set_table_reference(TableReference::default()/* use setters */);

pub fn set_or_clear_table_reference<T>(self, v: Option<T>) -> Self

where T: Into<TableReference>,

Sets or clears the value of table_reference.

Example

use google_cloud_bigquery_v2::model::TableReference;
let x = TableChangeInsight::new().set_or_clear_table_reference(Some(TableReference::default()/* use setters */));
let x = TableChangeInsight::new().set_or_clear_table_reference(None::<TableReference>);

pub fn set_metadata_cache_staleness_insight<T>(self, v: T) -> Self

where T: Into<MetadataCacheStalenessInsight>,

Sets the value of metadata_cache_staleness_insight.

Example

use google_cloud_bigquery_v2::model::MetadataCacheStalenessInsight;
let x = TableChangeInsight::new().set_metadata_cache_staleness_insight(MetadataCacheStalenessInsight::default()/* use setters */);

pub fn set_or_clear_metadata_cache_staleness_insight<T>( self, v: Option<T>, ) -> Self

where T: Into<MetadataCacheStalenessInsight>,

Sets or clears the value of metadata_cache_staleness_insight.

Example

use google_cloud_bigquery_v2::model::MetadataCacheStalenessInsight;
let x = TableChangeInsight::new().set_or_clear_metadata_cache_staleness_insight(Some(MetadataCacheStalenessInsight::default()/* use setters */));
let x = TableChangeInsight::new().set_or_clear_metadata_cache_staleness_insight(None::<MetadataCacheStalenessInsight>);

pub fn set_metadata_cache_not_used_but_used_previously<T>(self, v: T) -> Self

where T: Into<bool>,

Sets the value of metadata_cache_not_used_but_used_previously.

Example

let x = TableChangeInsight::new().set_metadata_cache_not_used_but_used_previously(true);

pub fn set_or_clear_metadata_cache_not_used_but_used_previously<T>( self, v: Option<T>, ) -> Self

where T: Into<bool>,

Sets or clears the value of metadata_cache_not_used_but_used_previously.

Example

let x = TableChangeInsight::new().set_or_clear_metadata_cache_not_used_but_used_previously(Some(false));
let x = TableChangeInsight::new().set_or_clear_metadata_cache_not_used_but_used_previously(None::<bool>);
