> The problem is that serialization of the `HoodieDeleteBlock` is generated dynamically by Kryo that could change whenever any class comprising it changes.
> We've been bitten by this already twice:
> HUDI-5758
> HUDI-4959
>  
> Instead, anything that is persisted on disk have to be serialized using hard-coded methods (same way HoodieDataBlock are serailized)
