This is what a row of your table will look like internally…

-------------------
RowKey: id-value
=> (column=date-value:request-value:, value=, timestamp=1359586739456000)
=> (column=date-value:request-value:data1, value=64617461312d76616c7565, timestamp=1359586739456000)
=> (column=date-value:request-value:data2, value=64617461322d76616c7565, timestamp=1359586739456000)

where id-value is the value of id column, and date-value is the….

So you need to construct triples for each column value. 
The first col name is the (date-value, request-value, empty) 
The second col name is (date-value, request-value, "data1") and has the value of data1. 

Hope that helps.

Hi,
 
 
I have some trouble to request my data. I use SSTableSimpleUnsortedWriter to write SSTable. Writing and Importing works fine.
I think, I’m misusing CompositeType.Builder with SSTableSimpleUnsortedWriter.
Do you have any idea ?
 
Thanks
 
Here is my case :
 
/**
* CREATE STATEMENT
*/
 
CREATE TABLE raw_data (
  id text,
  date text,
  request text,
  data1 text,
  data2 text,
  PRIMARY KEY (id, date, request)
) WITH
  bloom_filter_fp_chance=0.010000 AND
  caching='KEYS_ONLY' AND
  comment='' AND
  dclocal_read_repair_chance=0.000000 AND
  gc_grace_seconds=864000 AND
  read_repair_chance=0.100000 AND
  replicate_on_write='true' AND
  compaction={'class': 'SizeTieredCompactionStrategy'} AND
  compression={'sstable_compression': 'SnappyCompressor'};
 
/**
* JAVA CODE
*/
 
List<AbstractType<?>> compositeList = new ArrayList<AbstractType<?>>();
 
compositeList.add(UTF8Type.instance);
compositeList.add(UTF8Type.instance);
 
IPartitioner<?> partitioner = StorageService.getPartitioner();
dir = Directories.create(keyspace.getKeyspaceName(), columnFamily.getName()).getDirectoryForNewSSTables(0);
 
simpleUnsortedWriter = new SSTableSimpleUnsortedWriter(dir,
                                                               partitioner, keyspace.getKeyspaceName(),
                                                               columnFamily.getName(), UTF8Type.instance, null,
                                                               32);
 
CompositeType.Builder builderRequestDate = new CompositeType.Builder( CompositeType.getInstance                       (compositeList) );
CompositeType.Builder builderUrl = new CompositeType.Builder( CompositeType.getInstance(compositeList) );
 
simpleUnsortedWriter.newRow(bytes(id));
                              
builderRequestDate.add(bytes("date"));
builderRequestDate.add(bytes("request"));
 
long timestamp = System.currentTimeMillis() * 1000;
 
simpleUnsortedWriter.addColumn(builderRequestDate.build(),
                               bytes(date), timestamp);
simpleUnsortedWriter.addColumn(builderUrl.build(),
                               bytes(request), timestamp);
 
simpleUnsortedWriter.addColumn(bytes("data1"),
                               bytes(data1), timestamp);
simpleUnsortedWriter.addColumn(bytes("data2"),
                               bytes(data2), timestamp);
 
simpleUnsortedWriter.close();
