[FEATURE]: Add `static_multiset::count_outer`
sleeepyjack opened this issue · comments
Is your feature request related to a problem? Please describe.
static_multiset requires an equivalent function to static_multimap::count_outer.
Describe the solution you'd like
After #462 is finished, add a new API count_outer and also add a template parameter to the kernel to switch between count and count_outer behavior.
Describe alternatives you've considered
Still an open discussion if this is the best approach to tackle this problem but we couldn't come up with a better solution so far.
Additional context
No response
Similar to retrieve_outer, this API is probably cudf-specific and should take probe hash and probe key equal as arguments.
