---------------------------------------
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.
