Which option of the Manage Table Distribution tool do you use to evaluate if a partitioned table needs to be repartitioned?

The option to evaluate if a partitioned table needs to be repartitioned is focused on understanding the distribution of data across existing partitions. The choice that pertains to this evaluation process is assessing the number of partitions.

When determining if repartitioning is necessary, checking the number of partitions allows you to identify if they are balanced or imbalanced. An imbalanced distribution of data across partitions can lead to performance issues, as some partitions may end up being much larger than others, leading to inefficiencies during query execution or data processing.

In practice, if the number of partitions isn't optimal for the volume and characteristics of the data, it would indicate a need for adjustment—either consolidating smaller partitions or splitting larger ones to optimize performance. Thus, analyzing the number of partitions directly informs whether the current partitioning strategy is effective or if it requires modification, establishing this choice as the right option for evaluating the need for repartitioning.
