Interface Summary

Interface	Description
CustomSecondaryIndex<K extends Serializable,C extends Serializable & Comparable<C>,D>	Custom secondary index column family that keep rows from another column family (or main column family) as columns in wide rows.
Denormalizer<C extends Serializable & Comparable<C>,D>	Secondary index denormalizer.
SecondaryIndexIntegrator.SecondaryIndexReader<C extends Serializable & Comparable<C>>	Secondary index reader.
ShardStrategy<K extends Serializable,C>	Strategy used to distribute columns into multiple rows so they are handled by different nodes in Cassandra.

Class Summary

Class	Description
AllRowsSecondaryIndex<C extends Serializable & Comparable<C>,D>	Custom secondary index column family to keep all rows from another column family (or main column family) as columns in a wide row so they are counted and paged.
GenericCustomSecondaryIndex<K extends Serializable,C extends Serializable & Comparable<C>,D>	Generic implementation of CustomSecondaryIndex
HashShardStrategy<C>	Shard strategy to distribute column names into several row keys based on a hash function applied to the column value.
IndexEntryHandler<K extends Serializable>	Column family to keep indexes values to facilitate updating custom secondary indexes.
IndexEntryHandler.IndexEntry	Composite column name to keep the indexed attribute (or column name in the main column family) and a field to make the indexed value unique to avoid overriding previous values.
RangeLimit<T extends Serializable & Comparable<T>>	Range limit.
SecondaryIndexIntegrator	Workaround to support filter combinations in Cassandra similar to the relational model.
StringShardStrategy	Shard strategy to distribute String type column names into several row keys based on the first char (lower-case converted) of the String value.
