HA Generic¶

Generic high-availability cluster with fast switching times for different types of applications running in primary/secondary mode with data state preservation. Based on block synchronisation between nodes in synchronous or asynchronous mode. It can be used for various types of databases, state applications where it is necessary to quickly switch to a second node with data preservation if the first node fails or is temporarily unavailable. The cluster manager itself also works in primary / secondary mode without being a single point of failure.
