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
