GpuHostBatchCursor

query_runtime::runtime::resident

Struct GpuHostBatchCursor 

Source 
pub struct GpuHostBatchCursor { /* private fields */ }
Expand description

Bounded native GPU-to-host cursor retaining every owner required by the resident result until the final chunk is materialized or the cursor drops.

Implementations§

Source§

impl GpuHostBatchCursor

Source

pub fn prepare_next_batch(&self) -> Result<Option<GpuPreparedHostBatch>>

Size the next bounded host chunk without copying GPU values to host.

Source

pub fn materialize_prepared_batch( &mut self, prepared: GpuPreparedHostBatch, ) -> Result<RecordBatch>

Materialize one prepared chunk. Cancellation is checked after the host reservation is acquired and immediately before the device-to-host copy.
