Struct raftstore::store::fsm::apply::WaitSourceMergeState[−][src]

[+] Show declaration

struct WaitSourceMergeState {
    logs_up_to_date: Arc<AtomicU64>,
}

A struct that stores the state related to Merge.

When executing a CommitMerge, the source peer may have not applied to the required index, so the target peer has to abort current execution and wait for it asynchronously.

When rolling the stack, all states required to recover are stored in this struct. TODO: check whether generator/coroutine is a good choice in this case.

Fields

logs_up_to_date: Arc<AtomicU64>

A flag that indicates whether the source peer has applied to the required index. If the source peer is ready, this flag should be set to the region id of source peer.
