v.20.3New Feature
Support temporary data storage policy
Support storage policy (<tmp_policy>) for storing temporary data. #8750 (Azat Khuzhin)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.
