Description

What would you like to be improved?

Since #9927, we can add custom index properties when creating an index. As the GRANULARITY is always a constant value like 1 or 3, we need to make it configurable via index properties.

How should we improve?

Contributor guide

Research direction
Review PR #9927 to understand how custom index properties are added, then modify the index creation code to accept a configurable GRANULARITY value instead of hardcoded constant.
