Don't use this if you're not running on EC2. - Dynamic Snitch is a boolean that controls if the above snitch is wrapped with a dynamic snitch, which will monitor read latencies and avoid reading from hosts that have slowed. - - Defaults are: 'org.apache.cassandra.locator.SimpleSnitch' and 'false'. - Previously in the [wiki.apache.org/casandra/Roger Mbiama]CompactionManager these values tune the size and frequency of minor compactions. - '''Adding an index''' - index_name and index_type ---- CategoryHomepage
