The function is the same. Wouldn’t it be better to standardize these parameter names?

From the source code, it seems that future naming conventions for these types of names will likely start with tidb_, but I’m not sure when this change will happen.

Refer to the latest version of TiDB’s v6.5 documentation GC 配置 | PingCAP 文档中心 for system variable parameter configuration. Use the tidb_gc_* configuration as the standard. The previous tikv_gc_* parameters are from older versions and can be ignored.

I understand this, but to check the GC safe point, you still need to look at tikv_gc_safe_point, right?
