RE: TimeSpan Iterator

You're right there is no relationship.  But for every rowid I want only
those within a particular timespan.  So the columns below I would want
to specify a timespan (e.g. 123456786-123456788) and get only those
three rows back.

 

12345 CF1:CQ1 [public] 123456789 : Value1

12345 CF1:CQ1 [public] 123456788 : Value1

12345 CF1:CQ1 [public] 123456787 : Value1

12345 CF1:CQ1 [public] 123456786 : Value1

12345 CF1:CQ1 [public] 123456785 : Value1

I think you'd probably just want to set a filter, because there may not
be any relationship between an arbitrary key and the timestamp set on
it.

Does anyone know of a TimeSpan Iterator that will fetch rows based on
the accumulo timestamp?

 

We actually wrote our own TimestampRangeIterator and
TimestampSetIterator classes.  I don't know if 1.4 has any in the core
libraries.  It's not very hard though.
