Redis_failover 1.0 Released - Distributed monitoring, failover strategies, more (github.com)
redis_failover is a full failover solution for redis. As of v1.0, it now supports distributed monitoring among the Node Managers! Previously, the Node Managers were only used as a means of redundancy in case a particular node manager crashed. Starting with version 1.0 of redis_failover, the Node Managers will all periodically report their health report/snapshots. The primary Node Manager will utilize a configurable "node strategy" to determine if a particular node is available or unavailable.<p>redis_failover now supports a configurable "failover strategy" that's consulted when performing a failover. Currently, a single strategy is provided that takes into account the average latency of the last health check to the redis server.
