Juhani Connolly commented on FLUME-865:
---------------------------------------

Working on the configuration now, could use some input:

What shall we do when a sink group is invalidated because one of its sinks is 
missing? I see us as having 2 options, neither that I particularly like:
- Ignore the missing sink, only marking the group as invalid if it has no sinks
- Invalidate the set if any sinks are missing. The problem with this is that 
"unattached" sinks would then run independenly of a group, thus competing with 
one another for channel resources, when in normal functioning a group and its 
designated processor should be assigning work to each sink

> It would be nice if the flume-ng would have ability to failover to different 
> sink in case that the active one is not responding (e.g. before failing the 
> transaction).
