Alex Parvulescu commented on OAK-2104:
--------------------------------------

looks good!
two small things: 
 - first it the name should contain a dash: name + "LastIndexedTo" ->  'name + "-LastIndexedTo"
 - second I'm not too excited about putting a nodestore ref in there but as I understand from Chetan the property needs to be read from persistence each time to work in a cluster setup too, so it's good.

> Currently its not possible to determine how much the AsyncIndexUpdate is lagging behind in the indexing state i.e. its not possible to determine upto what time the repository state has been indexed. It would be helpful to expose this information such that a system admin can determing how much of recently added data is not indexed.
> This information can be determined by also storing the timestamp when a checkpoint is created as AsyncIndexUpdate would have indexed repository state upto that time
