[ANN] redis_failover 1.0 released

From: Ryan L.
Sent on: Friday, October 12, 2012 2:13 PM
I just released the big 1.0 release of redis_failover. redis_failover is a ZooKeeper-based automatic master/slave failover solution for Redis. Big changes in this release include:
  • redis_failover 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.
  • 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.
  • Improved handling of underlying ZK client connection in RedisFailover::NodeManager
  • Add support for passing in an existing ZK client instance to RedisFailover::Cient.new
  • Reduce unnecessary writes to ZK


Thanks,
Ryan
