All Implemented Interfaces:

Query<OrderedRows<K,N,V>>

public class IndexedSlicesQuery<K,N,V>
extends AbstractSliceQuery<K,N,V,OrderedRows<K,N,V>>

Uses new secondary indexes. Your CF must be configured for such to use this. The following creates an Indexed CF with the "birthday" column indexed (where birthdate represents a timestamp as it is validated by the LongType):

         - name: Indexed1
           column_metadata:
             - name: birthdate
               validator_class: LongType
               index_type: KEYS

setColumnNames

public IndexedSlicesQuery<K,N,V> setColumnNames(Collection<N> columnNames)

Description copied from class: AbstractSliceQuery

Sets the column names to be retrieved by this query

Overrides:

setColumnNames in class AbstractSliceQuery<K,N,V,OrderedRows<K,N,V>>

setColumnNames

public IndexedSlicesQuery<K,N,V> setColumnNames(N... columnNames)

Description copied from class: AbstractSliceQuery
