Ari Rabkin commented on CHUKWA-369:
-----------------------------------
When you say "server a" and "sever b", do you mean Agent A and B, or Collector
A and B?
For agent side first: The collector knows which chunk is written where in the
file, and it tells each agent where in the file its data will be.
For the collector side: There's exactly one collector per sink file, and when
an agent does a post, the collector tells it the filename to track.
Alright. I take your point that it's a mistake to have every collector doing
an LS. I can redesign so that only a handful of collectors are scanning the
filesystem -- reducing the load to an acceptable level. Would that address your
concerns?
