> Several times Ignite users faced a situation when SQL indexes were corrupted (linked to invalid or removed data).
> I think it makes sense to slightly rework such errors during index dereference, and
> 1) Fail all ongoing and further SQL queries assigned to this node. SQL mapper should cache this and try to re-route SQL requests to other OWNING nodes
> 2) After index corruption is detected, all or only corrupted indexes should be deallocated (the decision depends on what is faster) and rebuilt
> 3) After indexes are rebuilt, we should notify other nodes that the node is available for queries again
