      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.

      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

      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.

That said, we allow users to configure this if they're so inclined.
