The 23 design modes, in fact, the predecessors have summed up the ways to solve the problem. Their aim is to ensure the low coupling and high cohesion of the system. The principles guiding them are nothing more than the design principles of packaging change, single responsibility, interface-oriented programming, etc. After that, I will continue to share my WCF learning process. Although there are many WCF series in the blog park, I felt that it was not necessary to write them before, and I felt that I could use them. However, I did not write them. I always felt that the knowledge was not my own and I did not feel in-depth. Therefore, I still want to write such a series. I hope all bloggers will support me more.南雀使臣见何老将军等人都默然无语，心下松了口气。怀揣着漫画梦的少女田蕨苦命多年，就在她即将咸鱼翻身之日，因为一个吻，她与一个奇怪的男人建立了心灵感应。经过分析，这个男人便是她漫画的男主角，安白夜。然而，他不是什么漫穿人，而是真正的外星人。田蕨的脖子上佩戴的便是他多年来寻找的原石，他必须立即摘下原石拯救母星，但拿下原石，田蕨便会死。田蕨漫画梦的执念，使两人始终迟迟无法达成合作。安白夜决意，她实现漫画梦的那一天，便是他拿走原石之日。在此过程中，安白夜发现田蕨的身世，他们的命运居然早在十几年前便埋下了种子，而两人在朝夕相处中逐渐产生了情愫。长久以来，龙己（岛崎信长 配音）都过着独自一人的生活，表面看来，龙己性格冷淡不近人情，但实际上，他十分擅长料理家务，并且拥有一颗柔软的心灵。从某一日开始，龙己再也不是一个人了，而多出来的那一个“陪伴者”，竟然是寄宿在他家浴缸里的人鱼若狭（梅原裕一郎 配音）。……首先声明我不是变.态。Name of key parts, location, nature of use, construction area, fire resistance grade, presence or absence of fire fighting facilities, name of responsible person, ID card number and telephone number.In the last article, we explained Redis' master-slave cluster mode in detail. In fact, the configuration of this cluster mode is very simple. It only needs to be configured on Slave's nodes. The configuration of Master's master node does not need to be changed. However, one thing is that the persistent configuration of Master and Slave nodes should be consistent as far as possible, otherwise there will be strange problems. Starting today, we will begin to talk about the second mode of Redis cluster mode. That is, the "Sentinel" mode, which was provided from version 2.6 of Redis, but the mode of this version was unstable at that time. The Sentinel mode did not stabilize until version 2.8 of Redis. In the production environment, if you want to use the Sentinel mode of Redis, you will try to use the version after version 2.8 of Redis. Whether it is master-slave mode or sentinel mode, both modes have a problem and cannot be expanded horizontally, and the high availability of these two modes will be limited by the memory of Master master node. Another point is that the configuration of Sentinel mode is not simple or even complicated, so neither mode is recommended in industrial scenes. If you want to use it, you must have solutions to related problems to avoid subsequent problems.
