             Summary: IGFS: Open secondary file system stream on demand.
                 Key: IGNITE-3258
                 URL: https://issues.apache.org/jira/browse/IGNITE-3258
             Project: Ignite
          Issue Type: Sub-task
          Components: IGFS
    Affects Versions: 1.6
            Reporter: Vladimir Ozerov
            Assignee: Vladimir Ozerov
            Priority: Critical
             Fix For: 1.7


*Problem*
When we open a file in DUAL mode, we open secondary file system stream right away. However, in lots cases we will have data already available in memory, so that this stream is never used.

*Solution*
Let's open this stream on demand, i,e, only we understand that we miss require data chunk in data cache.
