Subject [jira] [Commented] (ACCUMULO-794) FirstEntryInRowIterator can scan through entire last row in range
Date Tue, 09 Oct 2012 20:06:02 GMT


Adam Fuchs commented on ACCUMULO-794:

I was thinking that would be non-trivial since this is a performance issue and not a correctness
issue. However, I suppose one could write a source iterator that complains if next is called
too many times in one row before seek is called. Still seems like more trouble than it's worth.

> If the range passed to the FirstEntryInRowIterator is seeked with a Range that has an
end key, the FirstEntryInRowIterator will scan through all of the entries in the last row
that match the range. This is due to a logic bug -- the if statement on line 93 needs an else
