SStable Writer and composite key

[POUGET Laurent]

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();
