the raft test, higher than Paxos (converted to 60 points, Raft scored 25.7,paxos score of 20.8), and figure 14 showed their respective scores. Pairing T-test shows that we have 95% confidence that the raft score distribution is at least 2.5 points higher than Paxos.We also set up a factor-based linear regression model to speculate on a new participant's quiz score: which test they used, their previous Paxos experience, and the order in which they learned the algorithm. The choice of model predi

inconsistencies by forcing the follower to copy its own logs. This means that the log entries in the follower will be overwritten by the leader. Section 5.4 will show that one more limit is more secure.To ensure that follower logs are consistent with their own, leader must find the most recent log entry in which two logs agree, delete all entries in the follower log, and send leader entries to follower. These actions will occur in a consistency check initiated by appendentries RPC. Leader maint

the ballot, the election timeout is randomly selected within a reasonable time interval (e.g. 150-300ms). This makes the server so that in most cases only one server wins the election; It wins the election and sends the heartbeat before the other server times out. The same processing mechanism is also used in the case of voting dispersion. Each candidate to restart its election timeout at the start of the election, and its overtime will continue to increase before the start of a new round of el

only transitions when Cnew is committed (always selecting leader from Cnew) because the new configuration can be manipulated independently. Before that, there may be only one cold server that can be elected leader.The third problem is that removing servers (those not in cnew) can disrupt the cluster. These servers will not receive a heartbeat and they will time out and start a new election. They will send the new term value of the Requestvote RPC, which will cause the incumbent leader to revert

we don't want this to Delay normal operations. The solution is to use copy-on-write techniques so this new updates can be accepted without impacting the snapshot being W Ritten. For example, the state machines built with functional data structures naturally. Alternatively, the operating system ' s copy-on-write support (e.g., fork on Linux) can is used to create an in-memory snaps Hot of the entire state machine (our implementation uses this approach).7th log CompressionDuring normal operation,

sections of this article.Raft first selects an outstanding leader and then gives it full responsibility for managing the log copy to achieve consistency. The leader receives log entries from the client, copies them to other servers, and tells them that it is safe to get log entries from the state machine. Only one leader simplifies the management of log replication. For example, the leader does not need to communicate with other servers to determine the location of log entries against the log,

-point number. It is worth mentioning that although the Zset structure uses both a skip table and a dictionary to hold an ordered set element, both data structures share the same members and scores through pointers, so using a skip table and a dictionary to save the collection element does not result in any duplicate members or scores, nor does it waste additional memory.Encoded conversionsWhen the party ordered collection object can meet the following two conditions, the object uses Ziplist enc
