public class LoadAllWarmUpStrategy
extends Object
implements WarmUpStrategy<LoadAllWarmUpConfiguration>

"Load all" warm-up strategy, which loads pages to persistent data region until it reaches DataRegionConfiguration.getMaxSize() with priority to index partitions. Loading occurs sequentially for each cache group, starting with index partition, and then all others in ascending order.
