Index - Are used to provide a speed improvement for fields that are often queried on, but comes at a memory cost and very minor cost for maintaining the index. Internally there are various types of indexes. These include CompactRangeIndex, RangeIndex, HashIndex, MapRangeIndex, CompactMapRangeIndex, PartitionedIndex and PrimaryKeyIndex
* RangeIndex - Uses a ConcurrentNavigableMap to store a key to store a RegionEntryToValuesMap. A RegionEntryToValuesMap is a map that uses the entry as the key and a struct as the value

* CompactRangeIndex - A memory efficient but slightly restricted version of RangeIndex. Will be preferred by the engine over range index if possible. Uses a ConcurrentNavigableMap to store a key and value pair, where the value can either be a RegionEntry, an IndexElemArray that contains RegionEntries or a IndexConcurrentHashSet that contains RegionEntries. The ConcurrentNavigableMap also is passed a Comparator that allows Indexes to match across different Numeric types.
