Analysis of Nacos source code

1. View the source code entry ： Look at the script

2. Nacos Client startup process ：nacos –>spring cloud Alibaba-> spring cloud –>spring boot -> spring
   Event listener
   3）nacos Asynchronous service registration ： Blocking queues Start a thread take

4）nacos Service registry ： double map Map<namespace, Map<group::serviceName, Service>> Cluster concept ？ Cluster refers to the cluster of service consumers When consuming services, start from nacos The server obtains the service list , Obtain corresponding services according to the principle of proximity
5） How to prevent read-write concurrency conflict in the service registry ？cow Read / write separation When writing copy Copy small particle size
6） Registry service changes PUSH / PULL nacos The server push transmission protocol is udp but udp It's possible to lose news
7）zk It's a long connection nacos yes http Short connection
8） Service change cow How did it happen ？
9）nacos ap colony
10）nacos client heartbeat Not to the original registered nacos server, How does the heartbeat synchronize ？ Be careful nacos server The heartbeat check timing task is specific to each service , That is, each service will start a heartbeat check scheduled task .
