> There is a single DynamicEndpointSnitch object for all ReplicationStrategy objects. This
DynamicEndpointSnitch object contains a single IEndpointSnitch subsnitch object. This subsnitch
object contains the Endpoint cache for a token. Thus there is a single endpoint cache for
all ReplicationStrategy objects. This implies that replica nodes for a Token as returned by
the Cache would be same irrespective of the ReplicationStrategy object. This is a bug, the
Endpoint cache should be a part of "AbstractReplicationStrategy" object rather than the IEndpointSnitch
object.
