問題文

The courier firm matches one data set against another. A group in the first set holds three thousand rows and the same group in the second set holds two thousand, and the tuning team works out how many pairs that will produce. The team then raises the execution instances on the transformation to shorten an identity matching run and expects the time to fall in step with the number it types. Which pairing is correct?

選択肢

1. The number of record pairs that a three thousand row group in one data set and a two thousand row group in the other produce is 6000000, and the gain in identity matching speed as the execution instances go up is uneven.
2. The number of record pairs that a three thousand row group in one data set and a two thousand row group in the other produce is 6000000, and the gain in identity matching speed as the execution instances go up is linear.
3. The number of record pairs that a three thousand row group in one data set and a two thousand row group in the other produce is 1999000, and the gain in identity matching speed as the execution instances go up is uneven.
