发送消息的进程称为主进程,接收消息的进程称为工作者进程。
Call the process sending the message the master process and the processes receiving the message the worker process.
它的架构基于一个使用工作者守护进程进行实际处理的中央服务器。
The architecture is based on a central server with worker daemons doing the real processing.
如果每个工作者节点都有DN和TT守护进程,每个守护进程在默认情况下占用1 GB内存,那么分配的总内存大约为4.8 GB。
If each worker node has both DN and TT daemons, and each daemon costs 1 GB memory by default, the total memory allocated would be around 4.8 GB.
