To enable this feature in TPC-DS benchmark, set To determine X: X = 576 / {executor instances} * ({scale factor} / 1000) For example, we have 18 executor instances, to run TPC-DS SF 1500, then X = 576 / 16 * 1500 / 1000 = 54. Then set If we don't have enough memory, replace 576 with a smaller value, at least 288. |
