>             Project: Apache Hudi
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 0.12.0
>            Reporter: Danny Chen
>            Assignee: Danny Chen
>            Priority: Major
>              Labels: pull-request-available
>             Fix For: 0.12.0

> Currently, we use short-cut logic:
> {code:java}
> a == b
> // for example: HoodieMergeHandle#writeUpdateRecord
> {code}
> to decide whether the update happens, in principle, we should not modify the records from disk directly, they should be kept as immutable, for any changes, we should return new records instead.
