Vladimir Ozerov commented on IGNITE-4953:
-----------------------------------------
Fixed. Data consistency is fine. However, there are some weird failures in
{{H2DynamicIndexSelfTest}} still.
> Rework logic of concurrent schema changes

>
> H2's prepared statements store references to indexes that were present when
> the statement was parsed and initialized - this means that currently there's
> no way to prevent index usage if it goes down between the moment when the
> statement is created and actually executed. Have to come up with some new
> locking schema.
