This PR introduces a
streamingoption to themap_batchesfunction. Whenstreaming=true, the user function will receive an iterator and return an iterator. This enables users to customize the streaming logic for data processing, such as parallelizing CPU and GPU operations to improve utilization of both resources. However, this approach is still not straightforward enough for users. In the future, we plan to allow users to pass multiple functions, which will automatically be executed in parallel across different threads in a pipelined manner.
