I hadn't been following the discussions regarding 0.8 and replication for a little while and this was a great post to refresh my memory and get up to speed on the current replication architecture's design.

Same here, summary was need as we have a fairly large ecosystem of multiple 0.7.2 clusters and I am planning to test upgrade to 0.8. However, one thing creeping at the back of my mind regarding 0.8 is something i have spotted in one thread few weeks ago namely that the rebalance behaviour of producers is not as robust as in 0.7.x without replication and i remeber there was no designed solution at the time - any news here ? Basically our usecase doesn't require replication but logical offsets and some other things introduced would solve some problems. On Feb 7, 2013 7:11 PM, "Vaibhav Puranik" <[EMAIL PROTECTED]> wrote:
So if the produces are partitioning by key we have to have replication if we dont want messages to get lost when partition goes down l right ? Thanks On Feb 8, 2013 5:12 AM, "Jun Rao" <[EMAIL PROTECTED]> wrote:
That's right. If you are partitioning by key, that means you insist a message has to go to a certain partition, whether it's available or not. So, if a partition is not available, we will drop the message for the partition in the async mode and consistently throw an exception to the caller in the sync mode.
