Guozhang Wang updated KAFKA-1762:
---------------------------------
Description:
The new Producer client introduces a config for the max # of inFlight messages.
When it is set > 1 on MirrorMaker, however, there is a risk for data loss even
after KAFKA-1650.
Another issue is that when this value is set > 1, there is a risk of message
re-ordering in the producer
Changes:
1. Set max # of inFlight messages = 1 in MM
2. Leave comments explaining what the risks are of changing
