The architecture of MegaStore is so complicated... There are so many roles in the system, e.g. stateless replicate server, different stateful paxos instances, stateful co-coordinator, bigtable and other auxilary roles. I suspect some roles are added later because the original implementation does not meet their design goal, as patch to normal software product. It is a nightmare for operation engineers of GAE. |
