Marcel Reutegger commented on OAK-763:
--------------------------------------

I like the general idea to use a branch for the checkpoint feature. Some 
questions:

Do we need two new methods for something very similar to the existing branches? 
Wouldn't it be better to change the existing branch method or introduce an 
overloaded version of NodeStore.branch() with a lifetime? I'd probably even 
favor a single branch method with a lifetime parameter. Wouldn't it be 
beneficial for the implementation to always have a hint on how long it must 
keep an un-merged branch?

Ah, I think now I understand why those two steps/methods are there. We need a 
marker that we can store in the index and later resume.

Alternatively we could move the checkpoint reference to NodeStoreBranch and 
have a single NodeStore.branch(@Nullable String branchRef, long lifetime).

> It would be good to have the possibility to update indexes asynchronously, 
> outside the current commit hook (or editor).
> This would be used for the index impls which can be a bit behind, like the 
> ones that do text extraction from binaries.
