> Index left partially built if a node crashes during index create or rebuild

> Key: IGNITE-8719
> URL: https://issues.apache.org/jira/browse/IGNITE-8719
> Project: Ignite
> Issue Type: Bug
> Reporter: Alexey Goncharuk
> Assignee: Sergey Antonov
> Priority: Critical
> Fix For: 2.8
>
> Attachments: IndexRebuildAfterNodeCrashTest.java,
> IndexRebuildingTest.java
>
>
> 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.
