> Project: Ignite
> Issue Type: Bug
> Components: sql
> Reporter: Alexey Goncharuk
> Assignee: Kirill Tkalenko
> 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.
