Examples of com.netflix.astyanax.Keyspace.prepareQuery()

com.netflix.astyanax.Keyspace.prepareQuery()
Starting point for constructing a query. From the column family the client can perform all 4 types of queries: get column, get key slice, get key range and and index query. @param < K> @param < C> @param cf Column family to be used for the query. The key and column serializers in the ColumnFamily are automatically used while constructing the query and the response.

      Key from = new Key(val, true);
      Key to = new Key(val, true);
      byte[] rowKey = scanInfo.getRowKey();
      
      CompositeRangeBuilder range = CassandraSession.setupRangeBuilder(from, to, info1, reverse);
      ColumnFamilyQuery query = keyspace.prepareQuery(cf);
      RowQuery<byte[], byte[]> rowQuery = query.getKey(rowKey).withColumnRange(range);
      Future future = executeAsync(rowQuery);
      futures.add(future);
    }
