Subject [jira] [Commented] (ACCUMULO-1471) SortedMapIterator.seek() doesn't respect columnFamilies
Date Wed, 29 May 2013 21:32:20 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1471?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13669762#comment-13669762
] 

John Vines commented on ACCUMULO-1471:
--------------------------------------

But I think SortedMapIterator should be treated just like an RFileReader. It is the MockAccumulo
equivalent after all. Sure, there currently are no optimizations for it (but there could be
by implementing locality groups via multimaps).

I mean, the fundamental problem I think, is that there are portions of the iterator arguments
that are not part of each iterator's contract, but rather an option that is known to be used
SOMEWHERE in the stack. We are not clear on this behavior, but it's something that had been
brought up in the work for ACCUMULO-652 because that brings in further options. I just remember
the column families between strange because they get used in multiple places in the stack.

> If you specify columnFamilies in a seek() on a SortedMapIterator, it will happily return
results from other column families.  The arguments are never even read.
