> Currently, index/table iterators can scan unpredictable count of cache
> entries during one {{hasNext()}}/{{next()}} call. These iterators contain
> filter, which applyed to each entry and row produced only for entries that
> satisfy filter. If filter contains "always false" rule, one {{hasNext()}}
> call may scan entiry table uninterruptably, without timeouts and yields to
> make another queries do their job. We should fix this behaviour.
