I think this KIP is not really about JBOD support it is just about remaining available in the presence of individual disk failures.
I agree this is nice to have but in the large scope of things is this really a big deal? Kafka deployments are usually a lot smaller than Hadoop deployments so even if you have 10% of your machines offline the total cost is not very much. In practice RAID doesn't actually solve this problem either, I don't think, because the I/O hit from rebuilding the RAID after a failure is so high you have to bring the server down anyway. I kind of agree with Todd's point that balancing data over individual disks might be a higher priority for making JBOD more practical. -Jay On Thu, Apr 9, 2015 at 5:36 AM, Andrii Biletskyi < andrii.bilets...@stealth.ly> wrote: > Hi, > > Let me start discussion thread for KIP-18 - JBOD Support. > > Link to wiki: > https://cwiki.apache.org/confluence/display/KAFKA/KIP-18+-+JBOD+Support > > > Thanks, > Andrii Biletskyi >
