Identifier

Identifies a unique leader epoch and log index “slot” into which a value may be proposed. Each leader must only propose a single value into any given slot and must change the BallotNumber to propose a different value at the same slot. The identifier used for a given slot will be shared across prepare, accept and commit messages during a leader take-over. The ordering of identifiers is defined by their log index order which is used to commit accepted values in order. TODO how can from differ from number.nodeIdentifier?

from: The node sending the message.
number: The paxos proposal number used for comparing messages, or values, as higher or lower than each other. This value will be fixed for a stable leadership.
logIndex: The contiguous log stream position, or “slot”, into which values are proposed and committed in order.
