> I've found that scanning lots of non-sequential single-row ranges is pretty
> slow in accumulo. Your best approach is probably to create an index table on
> whatever you are originally trying to query (assuming those 10000 ids came
> from some other query).
> {quote}
> Specifically, the use case is fetching many single items, all of which are
> present (so, bloom filters aren't going to help).
> Since this is one of the use cases Accumulo was designed to handle, look into
> actual performance and figure out if there are any obvious bottlenecks.
