>
> Lets say intial insert was done to partition1 and partition2. with col1 type as integer.
> commit2 inserted records to partition2 and partition3, with col1 type as long. integer -> long is backwards compatible evolution and hence write succeeds. but when trying to read data from hudi, we run into issues. This is not seen when a new column is added.
