Symbolic Links for Table Paths Based on Storage Policy

Official CH changelog text
Symbolic links for tables in the data/database_name/ directory are created for the actual paths to the table's data, depending on the storage policy, instead of the store/... directory on the default disk. #61777 (Kirill).
Creates symbolic links for tables in the data/database_name/ directory that point directly to the actual data paths based on the storage policy, instead of linking to the store/... directory on the default disk.

Why it matters

This feature improves the management and organization of table data by ensuring that symbolic links reflect the true storage location according to the configured storage policy. It solves confusion and potential issues related to the use of default disk storage links, making data paths more transparent and consistent.

How to use it

The feature is applied automatically when using storage policies that specify data storage locations. Users can observe that the symbolic links in the data/database_name/ directory now correctly point to the actual storage paths defined by their storage policies without additional configuration.
