* Loading everything while there is RAM with priority to indexes:
*org.apache.ignite.internal.processors.cache.warmup.LoadAllWarmUp*,
*org.apache.ignite.internal.processors.cache.warmup.LoadAllWarmUpConfiguration*
# Add a command to "control.sh", to stop current warm-up and cancel all others:
--warm-up stop
