-----------------------------------
Summary: 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: Siddharth Seth
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.
