Does partitioning query performance?
Administration of large tables can become easier with partitioning, and it can improve scalability and availability. In addition, a by-product of partitioning can be improved query performance.
Is Sharding partitioning?
Sharding and partitioning are both about breaking up a large data set into smaller subsets. The difference is that sharding implies the data is spread across multiple computers while partitioning does not. Partitioning is about grouping subsets of data within a single database instance.

How are Table partitions used in SQL pool?
Table partitions enable you to divide your data into smaller groups of data. In most cases, table partitions are created on a date column. Partitioning is supported on all dedicated SQL pool table types; including clustered columnstore, clustered index, and heap.
How are partitions processed in a tabular model?
Individual partitions, each containing a unique segment of data, can then be incrementally processed either sequentially or in parallel independent of other partitions, or excluded from processing operations altogether. By default, each table in a model has a single partition.
Do you have to have the same partition function as the base table?
An index does not have to participate in the same named partition function to be aligned with its base table. However, the partition function of the index and the base table must be essentially the same, in that: The arguments of the partition functions have the same data type. They define the same number of partitions.
