> 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.
