-All persistent state, such as the cluster metadata store and segments for the
services, are kept in the `var` directory under
-the Druid root directory, apache-druid-{{DRUIDVERSION}}. Each service writes
to a log file under `var/sv`.
+It may use up to 80% of the total available system memory.
+To explicitly set the total memory available to Druid, pass a value for the
memory parameter. For example, `./bin/start-druid -m 16g`.
+
+Druid stores all persistent state data, such as the cluster metadata store and
data segments, in `apache-druid-{{DRUIDVERSION}}/var`.
+Each service writes to a log file under `var/sv`.
At any time, you can revert Druid to its original, post-installation state by
deleting the entire `var` directory. You may want to do this, for example,
between Druid tutorials or after experimentation, to start with a fresh
instance.
To stop Druid at any time, use CTRL+C in the terminal. This exits the
`bin/start-druid` script and terminates all Druid processes.
