It does this by grouping machines into # "datacenters" and "racks." Cassandra will do its best not to have # more than one replica on the same "rack" (which may not actually # be a physical location) # # CASSANDRA WILL NOT ALLOW YOU TO SWITCH TO AN INCOMPATIBLE SNITCH # ONCE DATA IS INSERTED INTO THE CLUSTER. This would cause data loss. # This means that if you start with the default SimpleSnitch, which # locates every node on "rack1" in "datacenter1", your only options # if you need to add another datacenter are GossipingPropertyFileSnitch # (and the older PFS). From there, if you want to migrate to an # incompatible snitch like Ec2Snitch you can do it by adding new nodes # under Ec2Snitch (which will locate them in a new "datacenter") and # decommissioning the old ones. # # Out of the box, Cassandra provides: # # SimpleSnitch: # Treats Strategy order as proximity. This can improve cache # locality when disabling read repair. Only appropriate for # single-datacenter deployments. # # GossipingPropertyFileSnitch # This should be your go-to snitch for production use. The rack # and datacenter for the local node are defined in # cassandra-rackdc.properties and propagated to other nodes via # gossip. If cassandra-topology.properties exists, it is used as a # fallback, allowing migration from the PropertyFileSnitch. # # PropertyFileSnitch: # Proximity is determined by rack and data center, which are # explicitly configured in cassandra-topology.properties. # # Ec2Snitch: # Appropriate for EC2 deployments in a single Region. Loads Region # and Availability Zone information from the EC2 API. The Region is # treated as the datacenter, and the Availability Zone as the rack. # Only private IPs are used, so this will not work across multiple # Regions. # # Ec2MultiRegionSnitch: # Uses public IPs as broadcast_address to allow cross-region # connectivity. (Thus, you should set seed addresses to the public # IP as well.) You will need to open the storage_port or # ssl_storage_port on the public IP firewall. (For intra-Region # traffic, Cassandra will switch to the private IP after # establishing a connection.) # # RackInferringSnitch: # Proximity is determined by rack and data center, which are # assumed to correspond to the 3rd and 2nd octet of each node's IP # address, respectively. Unless this happens to match your # deployment conventions, this is best used as an example of # writing a custom Snitch class and is provided in that spirit. # # You can use a custom Snitch by setting this to the full class name # of the snitch, which will be assumed to be on your classpath. endpoint_snitch: SimpleSnitch # controls how often to perform the more expensive part of host score # calculation dynamic_snitch_update_interval_in_ms: 100 # controls how often to reset all host scores, allowing a bad host to # possibly recover dynamic_snitch_reset_interval_in_ms: 600000 # if set greater than zero and read_repair_chance is < 1.0, this will allow # 'pinning' of replicas to hosts in order to increase cache capacity. # The badness threshold will control how much worse the pinned host has to be # before the dynamic snitch will prefer other replicas over it. This is # expressed as a double which represents a percentage.

It's not that bare metal # doesn't benefit from coalescing messages, it's that the number of packets a bare metal network interface can process # is sufficient for many applications such that no load starvation is experienced even without coalescing. # There are other benefits to coalescing network messages that are harder to isolate with a simple metric like messages # per second. By coalescing multiple tasks together, a network thread can process multiple messages for the cost of one # trip to read from a socket, and all the task submission work can be done at the same time reducing context switching # and increasing cache friendliness of network message processing. # See CASSANDRA-8692 for details. # Strategy to use for coalescing messages in OutboundTcpConnection. # Can be fixed, movingaverage, timehorizon, disabled (default). # You can also specify a subclass of CoalescingStrategies.CoalescingStrategy by name. # otc_coalescing_strategy: DISABLED # How many microseconds to wait for coalescing. For fixed strategy this is the amount of time after the first # message is received before it will be sent with any accompanying messages.

The snitch has two functions: # # - it teaches Cassandra enough about your network topology to route # requests efficiently # - it allows Cassandra to spread replicas around your cluster to avoid # correlated failures. It does this by grouping machines into # "datacenters" and "racks." Cassandra will do its best not to have # more than one replica on the same "rack" (which may not actually # be a physical location) # # CASSANDRA WILL NOT ALLOW YOU TO SWITCH TO AN INCOMPATIBLE SNITCH # ONCE DATA IS INSERTED INTO THE CLUSTER. This would cause data loss. # This means that if you start with the default SimpleSnitch, which # locates every node on "rack1" in "datacenter1", your only options # if you need to add another datacenter are GossipingPropertyFileSnitch # (and the older PFS). From there, if you want to migrate to an # incompatible snitch like Ec2Snitch you can do it by adding new nodes # under Ec2Snitch (which will locate them in a new "datacenter") and # decommissioning the old ones. # # Out of the box, Cassandra provides: # # SimpleSnitch: # Treats Strategy order as proximity. This can improve cache # locality when disabling read repair. Only appropriate for # single-datacenter deployments. # # GossipingPropertyFileSnitch # This should be your go-to snitch for production use. The rack # and datacenter for the local node are defined in # cassandra-rackdc.properties and propagated to other nodes via # gossip. If cassandra-topology.properties exists, it is used as a # fallback, allowing migration from the PropertyFileSnitch. # # PropertyFileSnitch: # Proximity is determined by rack and data center, which are # explicitly configured in cassandra-topology.properties. # # Ec2Snitch: # Appropriate for EC2 deployments in a single Region. Loads Region # and Availability Zone information from the EC2 API. The Region is # treated as the datacenter, and the Availability Zone as the rack. # Only private IPs are used, so this will not work across multiple # Regions. # # Ec2MultiRegionSnitch: # Uses public IPs as broadcast_address to allow cross-region # connectivity. (Thus, you should set seed addresses to the public # IP as well.) You will need to open the storage_port or # ssl_storage_port on the public IP firewall. (For intra-Region # traffic, Cassandra will switch to the private IP after # establishing a connection.) # # RackInferringSnitch: # Proximity is determined by rack and data center, which are # assumed to correspond to the 3rd and 2nd octet of each node's IP # address, respectively. Unless this happens to match your # deployment conventions, this is best used as an example of # writing a custom Snitch class and is provided in that spirit. # # You can use a custom Snitch by setting this to the full class name # of the snitch, which will be assumed to be on your classpath. endpoint_snitch: "{{ cassandra_endpoint_snitch }}" # controls how often to perform the more expensive part of host score # calculation dynamic_snitch_update_interval_in_ms: 100 # controls how often to reset all host scores, allowing a bad host to # possibly recover dynamic_snitch_reset_interval_in_ms: 600000 # if set greater than zero and read_repair_chance is < 1.0, this will allow # 'pinning' of replicas to hosts in order to increase cache capacity. # The badness threshold will control how much worse the pinned host has to be # before the dynamic snitch will prefer other replicas over it.

It's not that bare metal # doesn't benefit from coalescing messages, it's that the number of packets a bare metal network interface can process # is sufficient for many applications such that no load starvation is experienced even without coalescing. # There are other benefits to coalescing network messages that are harder to isolate with a simple metric like messages # per second. By coalescing multiple tasks together, a network thread can process multiple messages for the cost of one # trip to read from a socket, and all the task submission work can be done at the same time reducing context switching # and increasing cache friendliness of network message processing. # See CASSANDRA-8692 for details. # Strategy to use for coalescing messages in OutboundTcpConnection. # Can be fixed, movingaverage, timehorizon, disabled (default). # You can also specify a subclass of CoalescingStrategies.CoalescingStrategy by name. # otc_coalescing_strategy: DISABLED # How many microseconds to wait for coalescing.
