László Bodor reassigned TEZ-1078:
---------------------------------
Assignee: László Bodor (was: Siddharth Seth)
> ValuesIterator does not need to deserialize keys for comparison
> ---------------------------------------------------------------
>
> Key: TEZ-1078
> URL: https://issues.apache.org/jira/browse/TEZ-1078
> Project: Apache Tez
> Issue Type: Improvement
> Reporter: Siddharth Seth
> Assignee: László Bodor
> Priority: Major
>
> ValuesIterator - which provides a Key, Values view - ends up deserializing
> each key before comparing it to the previous key when trying to determine
> whether a new key has been found or the next K-V pair in the IFile belongs to
> the same key.
> It should be possible to use the compare(byte[]. ...) method from the
> RawComparator interface.
