Hi All,

If I have a row with a set of keys as such:
- row1 cf:cq val
- row1 cf1:cq1 val
- row1 cf2:cq2 val
- row2 cf:cq val

Is there a way I can ask Accumulo to give me back all rows that have all
pairs (basically do an AND search): cf:cq, cf1:cq1, cf2:cq2. That way I
should only receive row1 back.

Thanks!
Roshan

I may be mistaken, but I believe the existing IntersectingIterator does not
function like that. However, it is possible to create an iterator that
performs this task.

Take a look at RowFilter in the ...core.iterators.user package.  It brings back rows that satisfy a condition specified in an abstract acceptRow method that is given an iterator over one particular row.
