Struct google_spanner1::ResultSetStats

pub struct ResultSetStats {
    pub row_count_lower_bound: Option<String>,
    pub row_count_exact: Option<String>,
    pub query_plan: Option<QueryPlan>,
    pub query_stats: Option<HashMap<String, String>>,
}

Additional statistics about a ResultSet or PartialResultSet.

This type is not used in any activity, and only used as part of another schema.

Fields

row_count_lower_bound: Option<String>

Partitioned DML does not offer exactly-once semantics, so it returns a lower bound of the rows modified.

row_count_exact: Option<String>

Standard DML returns an exact count of rows that were modified.

query_plan: Option<QueryPlan>

QueryPlan for the query associated with this result.

query_stats: Option<HashMap<String, String>>

Aggregated statistics from the execution of the query. Only present when the query is profiled. For example, a query could return the statistics as follows:

{
  "rows_returned": "3",
  "elapsed_time": "1.22 secs",
  "cpu_time": "1.19 secs"
}````
