> DocumentNodeState objects and other related data is currently identified with a String path in the various caches in the DocumentNodeStore. Read benchmarks like GetDeepNodeTest that only read data from memory are significantly slower on a DocumentNodeStore compared to a SegmentNodeStore. In these kind of tests the DocumentNodeStore is usually busy with String operations like constructing the path for a child node or calculating the hash code for a lookup in a cache.
> This issue is about a potential improvement that replaces the use of a plain String for the path of a DocumentNodeState and use a custom Path type instead.
