+# ARE PLACED.

+# 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.

+ <!-- Logging backends.
+ Cassandra 2.1+ moved to Logback. Titan is logging-backend-agnostic,
+ but still uses Log4j in testing. The slf4j binding for logback is,
+ inconveniently, packed into the logback-classic artifact. This means
+ the binding can't easily be removed from the classpath without losing
+ logback-classic or inserting some hack to mess with the jar contents.
+ We can't lose logback-classic because StorageProxy contains hardcoded
+ references to some of its classes (it contains some methods to change
+ logback loglevels at runtime). Hence, to stick with Log4j, the
+ least-worst approach is to enforce a classpath ordering constraint: as
+ long as the slf4j-log4j12 binding appears on the classpath before
+ logback-classic, log4j will be used instead of logback. I don't have
+ any special love for log4j, but Titan should use a single logging
+ backend throughout all its tests. I don't want to maintain a mixture
+ of logback.xml and log4j.properties files scattered randomly through
+ the titan-* submodules. Maven populates the classpath elements for
+ tests in pom appearance order. That's why these dependencies are
+ explicitly declared below: to make slf4j-log4j12 preced logback-classic
+ on the test classpath. -->

+ *
+ * This class once supported consecutive, idempotent calls to start(String) so

+ * many times as start(). Some of Cassandra's background threads and statics
+ * can't be easily reset to allow a restart inside the same JVM, so this was
+ * intended as a one-use thing. However, this interacts poorly with the new
+ * KCVConfiguration system in titan-core. When KCVConfiguration is in use, core
+ * starts and stops each backend at least twice in the course of opening a
+ * single database instance. So the old refcounting and killing approach is out.
