Sharad Agarwal commented on FLUME-1045:
---------------------------------------
This is indeed an useful feature for lot of folks. Since the goal of both the
jiras are same, I would recommend to do the work and capture all discussions at
the same place on this jira. It would be great if Inder and Jarek, you guys can
collaborate in design and implementation of this. make sense ?
Thanks!

> 1. Problem Description
> A sink being unavailable at any stage in the pipeline causes it to back-off
> and retry after a while. Channel's associated with such sinks start buffering
> data with the caveat that if you are using a memory channel it can result in
> a domino effect on the entire pipeline. There could be legitimate down times
> eg: HDFS sink being down for name node maintenance, hadoop upgrades.
> 2. Why not use a durable channel (JDBC, FileChannel)?
> Want high throughput and support sink down times as a first class use-case.
