Hi, Excellent work!
Before we mixed String and Path a lot, and have to split or concat string many times. In this PR, we use DetachedPath to replace String and uncertain Path (that we don't know it's a prefixPath or a measurement or others) until we get the full Path from metadata (Mtree). It's a great optimization! Julian Feinauer <[email protected]> 于2020年8月27日周四 下午4:36写道： > Ah thanks.
