Module lolraft::process

Structs

• Ballot

• Clock
  Clock of log entry. If two entries have the same clock, they should be the same entry. It is like the hash of the git commit.
• Entry
  Log entry.
• RaftProcess
  RaftProcess is a implementation of Raft process in RaftNode. RaftProcess is unaware of the gRPC and the network but just focuses on the Raft algorithm.

Traits

• RaftApp
  RaftApp is the representation of state machine in Raft. Beside the application state, it also contains the snapshot store where snapshot data is stored with a snapshot index as a key.
• RaftBallotStore
  RaftBallotStore is the representation of the ballot store in Raft. Conceptually, it is like RwLock<Ballot>.
• RaftLogStore
  RaftLogStore is the representation of the log store in Raft. Conceptually, it is like RwLock<BTreeMap<Index, Entry>>.

Type Aliases

• Index
  Log index.
• SnapshotStream
  Snapshot is transferred as stream of bytes. SnapshotStream is converted to gRPC streaming outside of the RaftProcess.`
• Term
  Election term. In Raft, only one leader can be elected per a term.
