CacheEntry<K,V> merge(CacheEntry<K,V> preferredEntry, List<CacheEntry<K,V>> otherEntries)
ConflictManager.resolveConflicts()for each conflict discovered to determine which
CacheEntryshould be utilised. This merge policy is used when a user explicitly calls
ConflictManager.resolveConflicts()as well as when a partition merge occurs with
PartitionHandling.ALLOW_READ_WRITESset. In the event of a partition merge, we define the preferred partition as the partition whom's coordinator is coordinating the current merge.
preferredEntry- During a partition merge, the preferred entry is the entry that belongs to the preferred partition. If multiple entries exist in the preferred partition, then the preferred entry is the primary owner in the preferred partition. If no entry exists in the preferred partition, then the preferredEntry is null. During a non-merge call to
ConflictManager.resolveConflicts(), the preferredEntry is simply the primary owner of an entry
