We implemented memory mapping channel that has memory channel performance and also file channel reliability. We plan to contribute it to open source in near future.

No. If you need to guarantee delivery of events please use a file channel.

I am using an upstream agent with a spooling directory source and a memory channel, and the downstream agent uses a memory channel and an HDFS sink. If my downstream agent goes down for any reason, are the entries lost in the downstream agent's memory channel still preserved in the memory channel / file directory of the upstream agent?

All the best, Chris
