-------------------------------------------

             Summary: Rework logic of concurrent schema changes
                 Key: IGNITE-4953
                 URL: https://issues.apache.org/jira/browse/IGNITE-4953
             Project: Ignite
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.0
            Reporter: Alexander Paschenko
            Assignee: Alexander Paschenko
             Fix For: 2.0


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.
