v.20.3New Feature

Support temporary data storage policy

Support storage policy (<tmp_policy>) for storing temporary data. #8750 (Azat Khuzhin)
Support for specifying a storage policy (<tmp_policy>) dedicated to storing temporary data in ClickHouse.

Why it matters

This feature enables users to define and use a separate storage policy for temporary data, improving management and optimization of temporary storage. It helps segregate temporary data from persistent data, allowing better resource allocation and potentially enhancing performance and maintainability.

How to use it

Users can define a storage policy for temporary data by specifying the <tmp_policy> parameter in the configuration or table definition. This policy will then be used by ClickHouse for storing all temporary data instead of the default storage policy.
