IntroducedOne important feature of Meta compared to Kafka is the implementation of the message high availability scenario, which we call the HA scenario. The message is written to the disk immediately after it is sent to the broker and returned to the client to tell the producer that the message was sent successfully, and the control of the unflushThreshold unflushInterval two parameters can guarantee the s

loops. These logs can record updates sent to the slave server. When an slaves server is connected to the master server, it notifies the master server of the last successful update location read from the server in the log. The server Load balancer receives any updates from that time, blocks them, and waits for the master server to notify you of new updates.

In a previous article on heartbeat as a solution for a highly available service architecture, today there is a new solution that uses keepalived to implement this feature.Keepalived is a high-performance server-ready or hot-standby solution, keepalived can be used to prevent a single point of failure of a server (a single point of failure is the failure of a certain point of the entire system architecture will be unavailable), The

Ha High Availability ClusterHA (high available) is highly available and is also known as dual-machine hot standby for critical business. Simple understanding, two machines Web1 and WEB2, Normal is Web1 provide services, WEB2 standby idle, when Web1 downtime or service outage, will automatically switch to WEB2 machine continue to provide services, WEB1 and WEB2 ha

Exchange Server 2010 uses a role-based management model. Multi-Role Server installation and configuration, we have in the previous article has been introduced. In this case, depending on high availability, we need to deploy the server roles on separate servers and achieve high availability of CAs, HT, and MBX roles. At
