Method Detail

mergeSortWithSv2

public void mergeSortWithSv2()
                      throws Exception

Tests the external sort using an in-memory sort. Relies on default memory settings to be large enough to do the in-memory sort (there is, unfortunately, no way to double-check that no spilling was done.) This must be checked manually by setting a breakpoint in the in-memory sort routine.

Parameters:
