Hello Hari:
Thanks for your question.But,I am using jdbc channel also use the file
channel.File channel has a problem when there is more than one source to the
file channel transmission the filechannel the Datadir accumulation of a large
number of files, the the hdfs sink can not quickly deal with these files, it
will cause a file lock is lost, so that can not continue, eventually leading to
the entire flume cluster comprehensive stop.In order to better monitor, I
therefore joined jdbc channel, how the number of event mangodb statistics can
prevent data loss.
So I want to get a good configuration for jdbc channel.

主题: Re: About jdbc channel
Is there any specific reason that you are using jdbc channel? I would
recommend using the FileChannel. The File Channel is what we would currently
recommend for use as a durable channel. We have improved the channel a lot in
the recent weeks. To take advantage of the latest features added to the
channel, you can build it and drop in the new jars, or wait for the next
release, which should happen soon.
Thanks,
Hari
