Riak Gets Better Reliability, Improved IPv6 Support
Riak 1.3.0 RC was recently released, with improved IPv6 support and some interesting features that improve reliability – Active Anti-Entropy and Health Check.
Active Anti-Entropy is a feature designed to be an additional layer of protection against data-corruption – it automatically detects missing or divergent data in replicas and triggers read repairs to correct the situation. This is designed to recover from various data loss situations such as disk-failure or restoring from out-dated backup. However this feature is currently limited to the Key/Value store and does not protect Riak Search data.
Other useful improvements -
Improved IPv6 support – Handoff and Protocol buffers can also now listen on IPv6 addresses (HTTP API already supported this)
Support for SmartOS 1.8
Riaknostic is now enabled by default
Health Check – a subsystem that actively monitors each node for specific condition and disables/enables services based on them
Ability to reset Bucket properties to default values
Support for logging to syslog
Detailed explanation of the new features as well as the complete list of bug-fixes are mentioned in the release notes.
