             Summary: .NET: Query cursors are not thread-safe
                 Key: IGNITE-12348
                 URL: https://issues.apache.org/jira/browse/IGNITE-12348
             Project: Ignite
          Issue Type: Bug
          Components: platforms
            Reporter: Pavel Tupitsyn
            Assignee: Pavel Tupitsyn


Query cursors (inheritors of {{QueryCursorBase}}) are not thread safe. The code 
has an attempt to make them thread-safe, but race condition exists between 
Dispose and MoveNext calls - it is possible that GetBatch is called after 
Dispose, causing all kinds of issues like calls to non-existent filter.

We should either fix the race, or update the documentation with a thread 
unsafety note.
