Nick Dimiduk commented on HBASE-10789:
--------------------------------------
Have a look at the
[DataType|http://hbase.apache.org/apidocs/org/apache/hadoop/hbase/types/DataType.html]
API. I think we could provide a DataTypeComparator that took into account the
presence of
[isOrderPreserving|http://hbase.apache.org/apidocs/org/apache/hadoop/hbase/types/DataType.html#isOrderPreserving()].
For implementations that are order preserving, it can do full ordering
efficiently. Of course, if the type isn't order preserving, it could
deserialize the values and compare them natively.
