To improve the performance of current queries on a temporal table, the table should be row partitioned. The table is logically divided into a set of current rows, and history rows (open rows and closed rows in the transaction-time dimension). Current queries are directed automatically to the partition containing current, open rows.

Column partitioning can also be applied to temporal tables, however the row partitioning described here should always constitute one of the partitioning types used for a temporal table.
