Struct ProfilingInfo 

pub struct ProfilingInfo {
    pub metrics: HashMap<String, String>,
    pub children: Vec<ProfilingInfo>,
}

ProfilingInfo is a recursive type containing metrics for each node in DuckDB’s query plan. There are two types of nodes: the “QUERY_ROOT” and “OPERATOR” nodes. The “QUERY_ROOT” refers exclusively to the top-level node; its metrics are measured over the entire query. The “OPERATOR” nodes refer to the individual operators in the query plan.

Fields

metrics: HashMap<String, String>

The metrics for the node, represented as a map from metric name to metric value. The actual format and units of the metric varies between metric kinds. For example,

• “ROWS_RETURNED” is an integer, formatted as a string
• “LATENCY” is a double-floating point number measuring the total query time in seconds, formatted as a string
• “OPERATOR_NAME” is a string
• “EXTRA_INFO” is a map of its own encoded as a string

children: Vec<ProfilingInfo>

The children of the node and their respective metrics.
