Struct HighCardinalityJoin 

#[non_exhaustive]
pub struct HighCardinalityJoin {
    pub left_rows: i64,
    pub right_rows: i64,
    pub output_rows: i64,
    pub step_index: i32,
    /* private fields */
}

High cardinality join detailed information.

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.

left_rows: i64

Output only. Count of left input rows.

right_rows: i64

Output only. Count of right input rows.

output_rows: i64

Output only. Count of the output rows.

step_index: i32

Output only. The index of the join operator in the ExplainQueryStep lists.

Implementations

impl HighCardinalityJoin

pub fn new() -> Self

Creates a new default instance.

pub fn set_left_rows<T: Into<i64>>(self, v: T) -> Self

Sets the value of left_rows.

Example

let x = HighCardinalityJoin::new().set_left_rows(42);

pub fn set_right_rows<T: Into<i64>>(self, v: T) -> Self

Sets the value of right_rows.

Example

let x = HighCardinalityJoin::new().set_right_rows(42);

pub fn set_output_rows<T: Into<i64>>(self, v: T) -> Self

Sets the value of output_rows.

Example

let x = HighCardinalityJoin::new().set_output_rows(42);

pub fn set_step_index<T: Into<i32>>(self, v: T) -> Self

Sets the value of step_index.

Example

let x = HighCardinalityJoin::new().set_step_index(42);
