Keeping logs forever

[Anthony Grimes]

Our use case is that we'd like to log data we don't need away and 
potentially replay it at some point. We don't want to delete old logs. I 
googled around a bit and I only discovered this particular post: 
http://mail-archives.apache.org/mod_mbox/incubator-kafka-users/201210.mbox/%3CCAFbh0Q2=eJcDT6NvTAPtxhXSk64x0Yms-G-AOqOoy=ftvvm...@mail.gmail.com%3E

In summary, it appears the primary issue is that Kafka keeps file 
handles of each log segment open. Is there a way to configure this, or 
is a way to do so planned? It appears that an option to deduplicate 
instead of delete was added recently, so doesn't the file handle issue 
exist with that as well (since files aren't being deleted)?
