Thanks to flowchart

Created with Raphaël 2.2.0Follower无法接收到Leader发出的Heartbeat(即Election Timeout)Follower变成Candidate时间序列Term++Candidate让剩下的nodes进行Vote其他的nodes进行voteCandidate获取到大多数nodes的投票Candidate变成Leader发送Heartbeat信息停止其他节点的electionyesno
FLOW:
init=>start: Follower无法接收到Leader发出的
Heartbeat(即Election Timeout)
be_candidate=>operation: Follower变成Candidate
时间序列Term++
vote=>operation: Candidate
让剩下的nodes
进行Vote
reply=>operation: 其他的nodes进行vote
become_leader=>condition: Candidate
获取到大多数
nodes的投票
become_leader_yes=>operation: Candidate变成Leader
send_heartbeat=>end: 发送Heartbeat信息
停止其他节点的election
init->be_candidate->vote->reply->become_leader
become_leader(yes)->become_leader_yes->send_heartbeat
become_leader(no)->be_candidate

3.4 树形结构

Thanks to Trent

Created with Raphaël 2.2.0

execute Runnable

执行的命令

LinkedBlockingQueue <Runnable>

线程池所使用的队列

keepAliveTime 0ms

当线程数大于 corePoolSize 时, 超出的线程的最大空闲时间, 在对队列进行poll的时候使用

maxPoolSize 100

执行任务的最大线程数. If there are more than corePoolSize but less than maximumPoolSize threads running, a new thread will be created only if the queue is full

corePoolSize 100

执行任务的线程数. When a new task is submitted, and fewer than corePoolSize threads are running, a new thread is created to handle the request, even if other worker threads are idle

ThreadPoolExecutor

Fixed Thread Pool Executor

TREE:
{
        text: { name: "Fixed Thread Pool Executor" },
        children: [
            {
                text: { name: "ThreadPoolExecutor" },
                children: [
                  {
                    text: {
                      name: "corePoolSize 100",
                      title: "执行任务的线程数. When a new task is submitted, and fewer than corePoolSize threads are running, a new thread is created to handle the request, even if other worker threads are idle"
                      }
                  },
                  {
                    text: {
                      name: "maxPoolSize 100",
                      title: "执行任务的最大线程数. If there are more than corePoolSize but less than maximumPoolSize threads running, a new thread will be created only if the queue is full"
                    },
                  },
                  { text: { name: "keepAliveTime 0ms", title: "当线程数大于 corePoolSize 时, 超出的线程的最大空闲时间, 在对队列进行poll的时候使用" } },
