Cloud Computing - Technical Foundations 31. What happens in case of errors at any of the replicas?: The write may have succeeded at the primary and an arbitrary subset of the secondary replicas. (If it had failed at the primary, it would not have been assigned a serial number and forwarded.) The client request is considered to have failed, and the modified region is left in an inconsistent state. Our client code handles such errors by retrying the failed mutation. 32. Why large write may cause consistent but undefined GFS regions?: GFS will break the write load into multiple write operations. While they follow proper write protocols, they may be interleaved with and overwritten by concurrent operations from other clients. Therefore, the region may end up containing fragments from different clients, although the write load chunks are identical at all replicas. This is why the region is consistent but undefined. 33. Control flow vs. Data flow: While control flows from the client to the primary and then to all secondaries, data is pushed linearly along a carefully picked chain of chunk servers in a pipelined fashion (to fully utilize network bandwidth - esp outbound) 34. How GFS dataflow avoid network bottlenecks and high-latency links (e.g., inter-switch links are often both) as much as possible?: each machine
