> Some tests are flaky because of minimal data size differences, e.g., one byte. However, many times we do not actually care about these differences. One example is {{default_constraint.q}}.
> Patch adds the possibility to mask printing of data size stats selectively on q files by adding the {{-- MASK_DATA_SIZE}} option.
