How to apply 'Reusing the Same Data History for Multiple Sliding Window Features' in sliding window config?

Thanks for your wonderful work, I want to use feathub in my project and want to know how to use Reusing the Same Data History for Multiple Sliding Window Features in my feature view config.

Hey @daugraph! FeatHub will recognize the opportunity to reuse the same data history when your program has multiple SlidingWindowTransform in the same SlidingFeatureView and those SlidingWindowTransform only differ in their window_size. You can find an example at https://github.com/flink-extended/feathub-examples/blob/master/flink-sliding-feature-view-benchmark/main.py#L78.
