- Built-in functions that are considered foldable by [!INCLUDE[ssNoVersion](../includes/ssnoversion-md.md)], including `CAST` and `CONVERT`. Generally, an intrinsic function is foldable if it is a function of its inputs only and not other contextual information, such as SET options, language settings, database options, and encryption keys. Nondeterministic functions are not foldable. Deterministic built-in functions are foldable, with some exceptions.

[!INCLUDE[ssKatmai](../includes/ssKatmai-md.md)] improved query processing performance on partitioned tables for many parallel plans, changes the way parallel and serial plans are represented, and enhanced the partitioning information provided in both compile-time and run-time execution plans. This topic describes these improvements, provides guidance on how to interpret the query execution plans of partitioned tables and indexes, and provides best practices for improving query performance on partitioned objects.
