Subject Re: High level technical overview of output bucketing for flume (old-gen) ?

Hi Bertrand,

I have written a blog about in 2011, here you can see for what you can see the use of bucketing:

You can use the sequences to create directories, based on the sequences the timestamp on a
syslog event will be delivered. So you have the availability to automatically create directories
for year, month, day, hour or something like that.
