Re: mirror maker and failover to another data center

Hi Kane, Unfortunately we do not have a perfect solution for this problem yet, since as you said the offsets on different DCs are different. At LinkedIn we bite the bullet on data duplication, i.e. when failover happens, the consumer queries the other DC for some offsets appended some time before

mirror maker and failover to another data center

2015-03-19 Thread Kane Kim
Hello, What's the best strategy for failover when using mirror-maker to replicate across datacenters? As I understand offsets in both datacenters will be different, how consumers should be reconfigured to continue reading from the same point where they stopped without data loss and/or duplication?
