Struct tidb_query_executors::interface::ExecuteStats[−][src]

pub struct ExecuteStats {
    pub summary_per_executor: Vec<ExecSummary, Global>,
    pub scanned_rows_per_range: Vec<usize, Global>,
}
[−]

Execution statistics to be flowed between parent and child executors at once during collect_exec_stats() invocation.

Fields

summary_per_executor: Vec<ExecSummary, Global>
[−]

The execution summary of each executor. If execution summary is not needed, it will be zero sized.

scanned_rows_per_range: Vec<usize, Global>
[−]

For each range given in the request, how many rows are scanned.

Implementations

impl ExecuteStats[src][−]

pub fn new(executors_len: usize) -> ExecuteStats[src][−]

Creates a new statistics instance.

If execution summary does not need to be collected, it is safe to pass 0 to the executors argument, which will avoid one allocation.

pub fn clear(&mut self)[src][−]

Clears the statistics instance.
