What one device partition counted for a layer beyond the shared record.

Fields

records: u64

Pre-dedup records over every fused block; on the permutation path, its input rows.

max_block_records: u32

The largest fused block’s records.

record_capacity: u32

Record capacity of the launched fused-layer variant.

batches: u32

Arena batches of the fused layer.

high_word_fallbacks: u32

Fused blocks that fell back to the high-word fingerprint passes, the sender-side merge’s included.

full_key_fallbacks: u32

Fused blocks that fell back to the full-key sort, the sender-side merge’s included.

rows_premerged: u64

Exported rows the sender-side merge folded away before the exchange.

rescaled: bool

The layer took the key-preserving rescale.

permuted: bool

The layer took the permutation path.

dense: bool

The fused layer reduced by the segmented scan rather than the head-serial walk.

Trait Implementations

impl Clone for DeviceLayerRecord

fn clone(&self) -> DeviceLayerRecord

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DeviceLayerRecord

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DeviceLayerRecord

fn default() -> DeviceLayerRecord

Returns the “default value” for a type.

impl PartialEq for DeviceLayerRecord

fn eq(&self, other: &DeviceLayerRecord) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
