public interface EntryBackupProcessor<K,V> extends Serializable
EntryProcessorcan see that a key exists but its backup processor
EntryBackupProcessormay not find it at run time due to an unsent backup of a previous operation (e.g. a previous put). In those situations, Hazelcast internally/eventually will sync those owner and backup partitions so you will not lose any data. When coding an
EntryBackupProcessor, you should take that case into account, otherwise
NullPointerExceptions can be seen since
Map.Entry.getValue()may return null.
