Using the Daemon Mode

The daemon in larger-scale testing can prevent potential skews in the test results by keeping the JVM warm.

The daemon is only available in tarball installations. Run the daemon from:

install_location/tools/bin/cassandra-stressd  start|stop|status  [-h  <host>]

During stress testing, you can keep the daemon running and send it commands through it using the --send-to option.

Example

Insert 1,000,000 rows to given host:
```
/tools/bin/cassandra-stress -node 192.168.1.101
```
When the number of rows is not specified, one million rows are inserted.
Read 1,000,000 rows from given host:
```
tools/bin/cassandra-stress read -node 192.168.1.101
```

Insert 10,000,000 rows across two nodes:

/tools/bin/cassandra-stress -node 192.168.1.101,192.168.1.102 n=10000000

Insert 10,000,000 rows across two nodes using the daemon mode:

/tools/bin/cassandra-stress -node 192.168.1.101,192.168.1.102 n=10000000 --send-to 54.0.0.1
