Managing partitions
Partitions in Analysis Services enable you to break up your data into manageable parts. Typically, you use them when you want to limit the amount of data you need to process in the model when the data is updated. Using our crash data table, we will add a new partition to the one that includes only crash data from January 1, 2015 onwards. Partitions are commonly created to break up large datasets based on common properties such as dates, regions, or stores. When you create a partition, only the data that matches the condition in the SQL statement will be inserted into each partition. In this recipe, you will create a new partition to move the crashes that occurred after 1/1/2012 to a new partition. Then you will edit the partition to limit the data to crashes that occurred prior to 1/1/2015.
