Type Parameters:

K -

All Implemented Interfaces:

com.netflix.astyanax.Execution<java.util.Map<K,java.lang.Integer>>, com.netflix.astyanax.query.RowSliceColumnCountQuery<K>

public class CqlRowSliceColumnCountQueryImpl<K>
extends java.lang.Object
implements com.netflix.astyanax.query.RowSliceColumnCountQuery<K>

Impl for RowSliceColumnCountQuery interface. Just like ColumnCountQuery, this class only manages the context for the query. The actual query statement is supplied from the CqlRowSliceQueryImpl class. Note that CQL3 treats columns as rows for certain schemas that contain clustering keys. Hence this class collapses all ResultSet rows with the same partition key into a single row when counting all unique rows.
