-y <TYPE> --family-type <TYPE> Sets the table type.
-f <FILE> --file <FILE> Write output to a given file.
-h --help Show help.
-k --keep-going Ignore errors when inserting or reading. When set, --keep-trying has no effect. Default is false.
-K <KEEP-TRYING> --keep-trying <KEEP-TRYING> Retry on-going operation N times (in case of failure). Use a positive integer. The default is 10.
-g <KEYS-PER-CALL> -g, --keys-per-call <KEYS-PER-CALL> Number of keys to per call. Default is 1000.
-d <NODES> --nodes <NODES> Nodes to perform the test against. Must be comma separated with no spaces. Default is localhost.
-D <NODESFILE> --nodesfile <NODESFILE> File containing host nodes (one per line).
-W --no-replicate-on-write Set replicate_on_write to false for counters. Only for counters with a consistency level of ONE (CL=ONE). See Counter columns in Data modeling.
-F <NUM-DIFFERENT-KEYS> --num-different-keys <NUM-DIFFERENT-KEYS> Number of different keys. If less than NUM-KEYS, the same key is re-used multiple times. Default is NUM-KEYS.
-n <NUMKEYS> --num-keys <NUMKEYS> Number of keys to write or read. Default is 1,000,000.
-p <PORT> --port <PORT> Thrift port. Default is 9160.
-i <PROGRESS-INTERVAL> --progress-interval <PROGRESS-INTERVAL> The interval, in seconds, at which progress is output. Default is 10 seconds.
-Q <QUERY-NAMES> --query-names <QUERY-NAMES> Comma-separated list of column names to retrieve from each row.
-r --random Use random key generator. When used --stdev has no effect. Default is false.
-l <REPLICATION-FACTOR> --replication-factor <REPLICATION-FACTOR> Replication Factor to use when creating tables. Default is 1.
-R <REPLICATION-STRATEGY> --replication-strategy <REPLICATION-STRATEGY> Replication strategy to use (only on insert and when a keyspace does not exist.) The default is SimpleStrategy.
-T <SEND-TO> --send-to <SEND-TO> Sends the command as a request to the cassandra-stressd daemon at the specified IP address. The daemon must already be running at that address.
-N <SKIP-KEYS> --skip-keys <SKIP-KEYS> Fraction of keys to skip initially. Default is 0.
-s <STDEV> --stdev <STDEV> Standard deviation. Default is 0.1.
-O <STRATEGY-PROPERTIES> --strategy-properties <STRATEGY-PROPERTIES> Replication strategy properties in the following format: <dc_name>:<num>,<dc_name>:<num>, .... For use with NetworkTopologyStrategy.
-t <THREADS> --threads <THREADS> Number of threads to use. Default is 50.
-m --unframed Use unframed transport. Default is false.
-P --use-prepared-statements (CQL only) Perform queries using prepared statements.
