怎么会有2主1从,是不是1主2从,还是说是1主备 + 一个单主? |

主从同步有性能损耗,从节点越多性能肯定更差 |

1:版本 RocketMQ5.1.3


2:jdk1.8
3:集群形态:DLedger Controller 模式
集群1:嵌入namesrv,3个节点(1个controller,2个broker+controller),1主1从
集群2:嵌入namesrv,5个节点(1个controller,2个broker+controller,2个broker),2主1从
4:现象
在使用./producer.sh测试生成tps时,发现1主1从的tps要明显高于2主1从的tps,那按照这种现象,如果多个主的话tps会很低的,岂不是性能很低。面对大数据量的情况下,是不是扩节点就会影响tps性能了?
