Duong updated RATIS-2094:
-------------------------
Description:
stateMachineLogEntry and stateMachineContext are parsed/created from
RaftClientRequest or LogEntryProto and attached to TransactionContext in the
StateMachine.startTransaction methods.
There are 2 variant of StateMachine.startTransaction;
1. startTransactions(RaftClientRequest): This is called only on the leader
side. The result of this method is not cached and is passed temporarily
alongside RaftClientRequest for further processing, for example. This is
probably safe.
2. startTransactions(LogEntryProto, RaftPeerRole): this is called on both
leader and follower side. The result of this call is cached on the node
* On leader: this is called right before applyTransaction to produce a
TransactionContext for StateMachine.applyTransaction.
* On follower: this is called when the appendEntries request is received. The
result is cached to be used by StateMachine.write and then
StateMachine.applyTransaction.
