+# endpoint_snitch -- Set this to a class that implements
+# IEndpointSnitch. 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)
+#
+# IF YOU CHANGE THE SNITCH AFTER DATA IS INSERTED INTO THE CLUSTER,
+# YOU MUST RUN A FULL REPAIR, SINCE THE SNITCH AFFECTS WHERE REPLICAS
+# ARE PLACED.
+#
+# Out of the box, Cassandra provides
+# - SimpleSnitch:
+# Treats Strategy order as proximity. This improves cache locality
+# when disabling read repair, which can further improve throughput.
+# Only appropriate for single-datacenter deployments.
+# - PropertyFileSnitch:
+# Proximity is determined by rack and data center, which are
+# explicitly configured in cassandra-topology.properties.
+# - GossipingPropertyFileSnitch
+# 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.
+# - 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 (as it did Facebook's), this is best used
+# as an example of writing a custom Snitch class.
+# - 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.)
+#
+# 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. Thus, a value of
+# 0.2 means Cassandra would continue to prefer the static snitch values
+# until the pinned host was 20% worse than the fastest.
+dynamic_snitch_badness_threshold: 0.1
+
+# request_scheduler -- Set this to a class that implements
+# RequestScheduler, which will schedule incoming client requests
+# according to the specific policy. This is useful for multi-tenancy
+# with a single Cassandra cluster.
+# NOTE: This is specifically for requests from the client and does
+# not affect inter node communication.
+# org.apache.cassandra.scheduler.NoScheduler - No scheduling takes place
+# org.apache.cassandra.scheduler.RoundRobinScheduler - Round robin of
+# client requests to a node with a separate queue for each
+# request_scheduler_id. The scheduler is further customized by
+# request_scheduler_options as described below.
+request_scheduler: org.apache.cassandra.scheduler.NoScheduler
+
+# Scheduler Options vary based on the type of scheduler
+# NoScheduler - Has no options
+# RoundRobin
+# - throttle_limit -- The throttle_limit is the number of in-flight
+# requests per client. Requests beyond
+# that limit are queued up until
+# running requests can complete.
+# The value of 80 here is twice the number of
+# concurrent_reads + concurrent_writes.
+# - default_weight -- default_weight is optional and allows for
+# overriding the default which is 1.
+# - weights -- Weights are optional and will default to 1 or the
+# overridden default_weight. The weight translates into how
+# many requests are handled during each turn of the
+# RoundRobin, based on the scheduler id.
+#
+# request_scheduler_options:
+# throttle_limit: 80
+# default_weight: 5
+# weights:
+# Keyspace1: 1
+# Keyspace2: 5
+
+# request_scheduler_id -- An identifier based on which to perform
+# the request scheduling. Currently the only valid option is keyspace.
+# request_scheduler_id: keyspace
+
+# index_interval controls the sampling of entries from the primrary
+# row index in terms of space versus time. The larger the interval,
+# the smaller and less effective the sampling will be. In technicial
+# terms, the interval coresponds to the number of index entries that
+# are skipped between taking each sample. All the sampled entries
+# must fit in memory. Generally, a value between 128 and 512 here
+# coupled with a large key cache size on CFs results in the best trade
+# offs. This value is not often changed, however if you have many
+# very small rows (many to an OS page), then increasing this will
+# often lower memory usage without a impact on performance.
+index_interval: 128
+
+# Enable or disable inter-node encryption
+# Default settings are TLS v1, RSA 1024-bit keys (it is imperative that
