Thomas Mueller commented on OAK-333:
------------------------------------

> So if the path exceeds a limit, the first limit/2 characters are replaced

See the comment above,

"One could even allow recursive replacement, so that there is no limit."

But actually I don't think recursion is needed. There are other solutions that 
don't require recursion, such as replace multiples of limit/2 bytes in once 
step.

I guess the next question will be what if the path is longer than 16 MB (the 
MongoDB limit for documents)? :-)

> In an infinite loop try to add nodes one under another to have N0/N1/N2...NN. 
> At some point, the current parent node will not be found and the current 
> commit will fail. I think this happens when the path length exceeds 1000 
> characters. Is this enough for a path? I was able to create this way only 222 
> levels in the tree (and my node names were really short N1, N2 ...)
> There's an automated tests for this: NodeExistsCommandMongoTest.testTreeDepth
