- *dynamic_snitch and endpoint_snitch
-  such Snitches, found in org.apache.cassandra.locator :
- 
- org.apache.cassandra.locator.SimpleSnitch which will do nothing,
- org.apache.cassandra.locator.RackInferringSnitch which will assume that the 2nd and 3rd
octets of the IP contain the datacenter and rack,
- org.apache.cassandra.locator.PropertyFileSnitch which will read from cassandra-topology.properties
to give explicit proximities, and
- org.apache.cassandra.locator.Ec2Snitch which will read the region and zone from the ec2
node and use them as datacenter and rack. 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.
