>            Reporter: Alexey Goncharuk

>            Priority: Critical

> Currently, we do not have any state associated with the index tree. Consider the following
scenario:
> 1) Start node, put some data
> 2) start CREATE INDEX operation
> 3) Wait for a checkpoint and stop node before index create finished
> 4) Restart node
> Since the checkpoint finished, the new index tree will be persisted to the disk, but
not all data will be present in the index.
> We should somehow store information about initializing index tree and mark it valid only
after all data is indexed. The state should be persisted as well.
