Trait sql_ops::join::cuda_radix_join::CudaRadixJoinable

pub trait CudaRadixJoinable: DeviceCopy + KeyAttribute {
    fn join_impl(
        rj: &CudaRadixJoin, 
        build_rel: &PartitionedRelation<Tuple<Self, Self>>, 
        probe_rel: &PartitionedRelation<Tuple<Self, Self>>, 
        result_set: &mut LaunchableMutSlice<'_, i64>, 
        task_assignments: &mut LaunchableMutSlice<'_, u32>, 
        stream: &Stream
    ) -> Result<()>;
}

Specifies that the implementing type can be used as a join key in CudaRadixJoin.

CudaRadixJoinable is a trait for which specialized implementations exist for each implementing type (currently i32 and i64). Specialization is necessary because each type requires a different CUDA function to be called.

Required methods

fn join_impl(
    rj: &CudaRadixJoin,
    build_rel: &PartitionedRelation<Tuple<Self, Self>>,
    probe_rel: &PartitionedRelation<Tuple<Self, Self>>,
    result_set: &mut LaunchableMutSlice<'_, i64>,
    task_assignments: &mut LaunchableMutSlice<'_, u32>,
    stream: &Stream
) -> Result<()>
