>
> During the execution of group by we adjust memory for the internal cache to
> keep all unique keys. We're increasing the number of keys by 1.5 factor and
> calculate how much space we need for it using SizedUtil.sizeOfMap, which is
> using ints as parameters and returns long. But since we are using all ints
> during the calculation, the integer overflow may happen and the method would
> return a negative value. As the result the query would fail, reporting that
> unable to allocate cache with negative size.
