        Because of the current BufferPool slab sizes of 64 KiB, we store in the file cache buffers that divide 64 KiB, so we need to round the buffer sizes to powers of two. This boolean controls weather they are rounded up or down. Set it to true to round up to the next power of two, set it to false to round down to the previous power of two. Note that buffer sizes are already rounded to 4 KiB and capped between 4 KiB minimum and 64 kb maximum by the Config.DiskOptimizationStrategy. By default, this boolean is set to round down when disk_optimization_strategy is ssd, and to round up when it is spinning.

      • user_defined_functions_threads_enabled

        public boolean user_defined_functions_threads_enabled
        Optionally disable asynchronous UDF execution. Disabling asynchronous UDF execution also implicitly disables the security-manager! By default, async UDF execution is enabled to be able to detect UDFs that run too long / forever and be able to fail fast - i.e. stop the Cassandra daemon, which is currently the only appropriate approach to "tell" a user that there's something really wrong with the UDF. When you disable async UDF execution, users MUST pay attention to read-timeouts since these may indicate UDFs that run too long or forever - and this can destabilize the cluster. This requires allow_insecure_udfs to be true

      • allow_insecure_udfs

        public boolean allow_insecure_udfs
        Set this to true to allow running insecure UDFs.

      • allow_extra_insecure_udfs

        public boolean allow_extra_insecure_udfs
        Set this to allow UDFs accessing java.lang.System.* methods, which basically allows UDFs to execute any arbitrary code on the system.

      • user_defined_functions_fail_timeout

        public DurationSpec.LongMillisecondsBound user_defined_functions_fail_timeout
        Time in milliseconds after a fatal UDF run-time situation is detected and action according to user_function_timeout_policy will take place. (Only valid, if user_defined_functions_threads_enabled==true)

      • user_function_timeout_policy

        public Config.UserFunctionTimeoutPolicy user_function_timeout_policy
        Defines what to do when a UDF ran longer than user_defined_functions_fail_timeout. Possible options are: - 'die' - i.e. it is able to emit a warning to the client before the Cassandra Daemon will shut down. - 'die_immediate' - shut down C* daemon immediately (effectively prevent the chance that the client will receive a warning). - 'ignore' - just log - the most dangerous option. (Only valid, if user_defined_functions_threads_enabled==true)

      • block_for_peers_timeout_in_secs

        public int block_for_peers_timeout_in_secs
        When a node first starts up it intially considers all other peers as DOWN and is disconnected from all of them. To be useful as a coordinator (and not introduce latency penalties on restart) this node must have successfully opened all three internode TCP connections (gossip, small, and large messages) before advertising to clients. Due to this, by default, Casssandra will prime these internode TCP connections and wait for all but a single node to be DOWN/disconnected in the local datacenter before offering itself as a coordinator, subject to a timeout. See CASSANDRA-13993 and CASSANDRA-14297 for more details. We provide two tunables to control this behavior as some users may want to block until all datacenters are available (global QUORUM/EACH_QUORUM), some users may not want to block at all (clients that already work around the problem), and some users may want to prime the connections but not delay startup. block_for_peers_timeout_in_secs: controls how long this node will wait to connect to peers. To completely disable any startup connectivity checks set this to -1. To trigger the internode connections but immediately continue startup, set this to to 0. The default is 10 seconds. block_for_peers_in_remote_dcs: controls if this node will consider remote datacenters to wait for. The default is to _not_ wait on remote datacenters.

        public volatile boolean repaired_data_tracking_for_range_reads_enabled
        flags for enabling tracking repaired state of data during reads separate flags for range & single partition reads as single partition reads are only tracked when CL > 1 and a digest mismatch occurs. Currently, range queries don't use digests so if enabled for range reads, all such reads will include repaired data tracking. As this adds some overhead, operators may wish to disable it whilst still enabling it for partition reads

        public volatile int denylist_max_keys_per_table
        We cap the number of denylisted keys allowed per table to keep things from growing unbounded. Operators will receive warnings and only denylist_max_keys_per_table in natural query ordering will be processed on overflow.

      • denylist_max_keys_total

        public volatile int denylist_max_keys_total
        We cap the total number of denylisted keys allowed in the cluster to keep things from growing unbounded. Operators will receive warnings on initial cache load that there are too many keys and be directed to trim down the entries to within the configured limits.

      • denylist_consistency_level

        public ConsistencyLevel denylist_consistency_level
        Since the denylist in many ways serves to protect the health of the cluster from partitions operators have identified as being in a bad state, we usually want more robustness than just CL.ONE on operations to/from these tables to ensure that these safeguards are in place. That said, we allow users to configure this if they're so inclined.

      • snapshot_on_duplicate_row_detection

        public volatile boolean snapshot_on_duplicate_row_detection
        If true, when rows with duplicate clustering keys are detected during a read or compaction a snapshot will be taken. In the read case, each a snapshot request will be issued to each replica involved in the query, for compaction the snapshot will be created locally. These are limited at the replica level so that only a single snapshot per-day can be taken via this method.

        If true, a quorum will be required for the global and local quorum checks. If false, we will accept a quorum OR n - 1 live nodes. This is to allow for topologies like 2:2:2, where paxos queries always use SERIAL, and a single node down in a dc should not preclude a paxos repair
