      • JAVA_RMI_SERVER_HOSTNAME

        public static final CassandraRelevantProperties JAVA_RMI_SERVER_HOSTNAME
        The value of this property represents the host name string that should be associated with remote stubs for locally created remote objects, in order to allow clients to invoke methods on the remote object.

      • JAVA_RMI_SERVER_RANDOM_ID

        public static final CassandraRelevantProperties JAVA_RMI_SERVER_RANDOM_ID
        If this value is true, object identifiers for remote objects exported by this VM will be generated by using a cryptographically secure random number generator. The default value is false.

      • COM_SUN_MANAGEMENT_JMXREMOTE_AUTHENTICATE

        public static final CassandraRelevantProperties COM_SUN_MANAGEMENT_JMXREMOTE_AUTHENTICATE
        This property indicates whether password authentication for remote monitoring is enabled. By default it is disabled - com.sun.management.jmxremote.authenticate

      • COM_SUN_MANAGEMENT_JMXREMOTE_RMI_PORT

        public static final CassandraRelevantProperties COM_SUN_MANAGEMENT_JMXREMOTE_RMI_PORT
        The port number to which the RMI connector will be bound - com.sun.management.jmxremote.rmi.port.

      • BOOTSTRAP_SKIP_SCHEMA_CHECK

        public static final CassandraRelevantProperties BOOTSTRAP_SKIP_SCHEMA_CHECK
        When bootstraping we wait for all schema versions found in gossip to be seen, and if not seen in time we fail the bootstrap; this property will avoid failing and allow bootstrap to continue if set to true.

      • BOOTSTRAP_SCHEMA_DELAY_MS

        public static final CassandraRelevantProperties BOOTSTRAP_SCHEMA_DELAY_MS
        When bootstraping how long to wait for schema versions to be seen.

        public static final CassandraRelevantProperties DRAIN_EXECUTOR_TIMEOUT_MS
        When draining, how long to wait for mutating executors to shutdown.

      • GOSSIPER_QUARANTINE_DELAY

        public static final CassandraRelevantProperties GOSSIPER_QUARANTINE_DELAY
        Gossip quarantine delay is used while evaluating membership changes and should only be changed with extreme care.

      • REPLACEMENT_ALLOW_EMPTY

        public static final CassandraRelevantProperties REPLACEMENT_ALLOW_EMPTY
        When doing a host replacement its possible that the gossip state is "empty" meaning that the endpoint is known but the current state isn't known. If the host replacement is needed to repair this state, this property must be true.

      • CASSANDRA_FOREGROUND

        public static final CassandraRelevantProperties CASSANDRA_FOREGROUND
        The cassandra-foreground option will tell CassandraDaemon whether to close stdout/stderr, but it's up to us not to background. yes/null

      • ORG_APACHE_CASSANDRA_DISABLE_MBEAN_REGISTRATION

        public static final CassandraRelevantProperties ORG_APACHE_CASSANDRA_DISABLE_MBEAN_REGISTRATION

      • ORG_APACHE_CASSANDRA_CONF_CASSANDRA_RELEVANT_PROPERTIES_TEST

        public static final CassandraRelevantProperties ORG_APACHE_CASSANDRA_CONF_CASSANDRA_RELEVANT_PROPERTIES_TEST

      • ORG_APACHE_CASSANDRA_DB_VIRTUAL_SYSTEM_PROPERTIES_TABLE_TEST

        public static final CassandraRelevantProperties ORG_APACHE_CASSANDRA_DB_VIRTUAL_SYSTEM_PROPERTIES_TABLE_TEST

      • IS_DISABLED_MBEAN_REGISTRATION

        public static final CassandraRelevantProperties IS_DISABLED_MBEAN_REGISTRATION
        This property indicates whether disable_mbean_registration is true

      • MBEAN_REGISTRATION_CLASS

        public static final CassandraRelevantProperties MBEAN_REGISTRATION_CLASS
        what class to use for mbean registeration

      • SCHEMA_PULL_INTERVAL_MS

        public static final CassandraRelevantProperties SCHEMA_PULL_INTERVAL_MS
        Defines how often schema definitions are pulled from the other nodes

      • SCHEMA_PULL_BACKOFF_DELAY_MS

        public static final CassandraRelevantProperties SCHEMA_PULL_BACKOFF_DELAY_MS
        Minimum delay after a failed pull request before it is reattempted. It prevents reattempting failed requests immediately as it is high chance they will fail anyway. It is better to wait a bit instead of flooding logs and wasting resources.

      • USE_NIX_RECURSIVE_DELETE

        public static final CassandraRelevantProperties USE_NIX_RECURSIVE_DELETE
        When enabled, recursive directory deletion will be executed using a unix command `rm -rf` instead of traversing and removing individual files. This is now used only tests, but eventually we will make it true by default.

      • NON_GRACEFUL_SHUTDOWN

        public static final CassandraRelevantProperties NON_GRACEFUL_SHUTDOWN
        If set, MessagingService is shutdown abrtuptly without waiting for anything. This is an optimization used in unit tests becuase we never restart a node there. The only node is stopoped when the JVM terminates. Therefore, we can use such optimization and not wait unnecessarily.

      • FLUSH_LOCAL_SCHEMA_CHANGES

        public static final CassandraRelevantProperties FLUSH_LOCAL_SCHEMA_CHANGES
        Flush changes of SchemaKeyspace after each schema modification. In production, we always do that. However, tests which do not restart nodes may disable this functionality in order to run faster. Note that this is disabled for unit tests but if an individual test requires schema to be flushed, it can be also done manually for that particular case: flush(SchemaConstants.SCHEMA_KEYSPACE_NAME);.
