Description

Is this a new feature, an improvement, or a change to existing functionality?

New Feature

How would you describe the priority of this feature request

Nice to have (e.g. Adoption is possible, the feature will enhance the use-case even more).

Please provide a clear description of problem this feature solves

Instantiating the dali dataloader for jax takes a long time, because of prefetching.

Feature Description

It would be nice to have an asynchronous prefetching feature, so I can interleave jitting the model and the prefetching operations.

Describe your ideal solution

Have two function

def start_async_prefetch(self):

def block_till_ready_async_prefetch():

With these two functions, I can control when prefetching happens

Describe any alternatives you have considered
