-----------------------------------
Summary: LevelDbKeyValueStore range implements 'from' -> 'to'
instead of 'from' -> 'until'
Key: SAMZA-326
URL: https://issues.apache.org/jira/browse/SAMZA-326
Project: Samza
Issue Type: Bug
Reporter: Chinmay Soman
Priority: Minor
Most built-in ordered collection data structures in Java (SortedMap, List, ...)
define a range (submap / sublist) as follows:
'from' (inclusive) -> 'until' (exclusive)
However, the current LevelDbKeyValueStore implementation defines range as:
'from' (inclusive) -> 'to' (inclusive)
While this is not technically incorrect, I think we should change the semantics
to follow the norm.
P.S. This can easily be done by changing the '<=' comparison in
LevelDbRangeIterator to '<'
