[jira] [Created] (IGNITE-11300) MVCC: forbid using DataStreamer with allowOverwrite=true

Ivan Pavlukhin created IGNITE-11300:
---------------------------------------

             Summary: MVCC: forbid using DataStreamer with allowOverwrite=true
                 Key: IGNITE-11300
                 URL: https://issues.apache.org/jira/browse/IGNITE-11300
             Project: Ignite
          Issue Type: Task
          Components: mvcc
    Affects Versions: 2.7
            Reporter: Ivan Pavlukhin
             Fix For: 2.8


Calling {{IgniteDataStreamer.allowOverwrite(true)}} configures a streamer to use single-key cache put/remove operations for data modification. But put/remove operations on MVCC caches can be aborted due to write conflicts. So, some development effort is needed to support that mode properly. Let's throw exception in such case for MVCC caches.
