------------------------------------
Thanks you replay
When I studied the Kafka source code， I find class `ContextualRecord` have an
attribute is `ProcessorRecordContext` object and
`ProcessorRecordContext#toString()` be deprecated.
I am considering whether to also deprecate `ContextualRecord#toString()`. But
it seems unnecessary, so I raised this issue
> ContextualRecord#hashCode()、ProcessorRecordContext#hashCode() Should not be
> deprecated and throw an exception

> when review PR#16970。 I find function

> hashCode to change。
> I don't think that hashCode should be discarded just because it is mutable.
> HashCode is a very important property of an object. It just shouldn't be used
