Apply_grouped - is it sequential like apply?

Regarding RAPIDS ‘apply_grouped’ function after groupby - if we write a custom Numba kernel for the grouped object, does it process the groups sequentially or in parallel ?

The documentation shows that the ‘apply’ function does it in sequence as documented here: GroupBy — cudf 22.02.00 documentation

But, I was unable to find any info for ‘apply_grouped’ in the docs.

Thanks !
