             Summary: Add Warning message for multiple data streamers
                 Key: IGNITE-9295
                 URL: https://issues.apache.org/jira/browse/IGNITE-9295
             Project: Ignite
          Issue Type: Improvement
            Reporter: Alexander Gerus
             Fix For: 2.7


DataStreamer is design to allocate as much resources as available. In case if user is starting more then one instance per cache, it can cause significant slowdown for the streaming due to significant consumption of resources 

The proposal is to add warning message to the application log in case if two or more data streamers per cache:

Warning Text: “DataStreamer is already running. For best performance please use single instance”

The warning should be printed only once when the case is detected
