 * To execute this script you will have to enable optional `ignite-rest-http` module -

 *
 * After that start up an instance of Ignite with cache enabled.
 * You can use configuration from examples/config folder as follows:
 * ----
 * ${IGNITE_HOME}/bin/ignite.sh examples/config/example-cache.xml
 * ----
 *
 * Make sure you have correctly specified $CACHE_NAME script global variable
 * accordingly to your configuration. In mentioned above example-cache.xml we
 * have only default cache configured.
