Mike, so when the data is committed to the channel, and the channel is of
type "File" then when the agent will be restarted the data will continue to
flow onto the sink?
And if only 20% of the data passed onto the sink before it crashed then a
"Replay" will be done to resend the whole data?
Just trying to grasp the basics....
