Enum BackendAttemptDisposition 

Source 
#[repr(usize)]
pub enum BackendAttemptDisposition {
    Unplanned = 0,
    CpuFallback = 1,
    PartialNative = 2,
    Native = 3,
}
Expand description

Closed disposition dimension of terminal backend-attempt metrics.

Variants§

§

Unplanned = 0

No classified physical plan was obtained.

§

CpuFallback = 1

The plan used DataFusion execution without native operators.

§

PartialNative = 2

The plan combined native and DataFusion execution.

§

Native = 3

The plan had native execution coverage.
