問題文

You check which rows an incremental run took in once its start value is reported, and what a full load does to the data that the target already holds. Which pair completes this sentence correctly?

選択肢

  1. the rows that an incremental run with an ID key took in, when the start value reported for that run is 2500, are the ones whose ID misses that value but rises above it, and the data that a Hive or an HDFS target already holds when a full load runs is kept intact
  2. the rows that an incremental run with an ID key took in, when the start value reported for that run is 2500, are the ones whose ID matches that value or rises above it, and the data that a Hive or an HDFS target already holds when a full load runs is kept intact
  3. the rows that an incremental run with an ID key took in, when the start value reported for that run is 2500, are the ones whose ID matches that value or rises above it, and the data that a Hive or an HDFS target already holds when a full load runs is swept aside
  4. the rows that an incremental run with an ID key took in, when the start value reported for that run is 2500, are the ones whose ID misses that value but rises above it, and the data that a Hive or an HDFS target already holds when a full load runs is swept aside
