> The external sort operator has a memory limit based on, among other things, the MAX_QUERY_MEMORY_PER_NODE constant. This constant is 2048 and it is assumed the caller will multiply by the appropriate factor to get the number of bytes.
> The setting for external sort is not doing so.
> It is better to fix the constant to specify the exact value in bytes.
