+#          may be limited depending on use of stack space).
+#
+# hsha  -> Stands for "half synchronous, half asynchronous." All thrift clients are handled
+#          asynchronously using a small number of threads that does not vary with the amount
+#          of thrift clients (and thus scales well to many clients). The rpc requests are still
+#          synchronous (one thread per active request). If hsha is selected then it is essential
+#          that rpc_max_threads is changed from the default value of unlimited.
+#
+# The default is sync because on Windows hsha is about 30% slower.  On Linux,
+# sync/hsha performance is about the same, with hsha of course using less memory.

+
+# Uncomment rpc_min|max_thread to set request pool size limits.

+# Regardless of your choice of RPC server (see above), the number of maximum requests in the

+# endpoint_snitch -- Set this to a class that implements

+# - it teaches Cassandra enough about your network topology to route

+# - 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 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.
