Thank you Aaaron!
Your blog post helped me understand how a row with a compound key is stored and
this helped me understand how to create the sstable files.
For anyone who needs it this is how it works:
In Cassandra-cli the row looks like this:
RowKey: 5
=> (column=10:created, value=0000013f84be6288, timestamp=1372321637000000)
>From this we see that the row key is a single Long value "5", and it has one
>composite column "10:created" with a timestamp value.
Thus the code should look like this:
File directory = new File( System.getProperty( "output" ) );
IPartitioner partitioner = new Murmur3Partitioner();
String keyspace = "test_keyspace";
String columnFamily = "test_table";
List<AbstractType<?>> compositeList = new ArrayList<AbstractType<?>>();
compositeList.add( LongType.instance );
compositeList.add( LongType.instance );
CompositeType compositeType = CompositeType.getInstance( compositeList );
SSTableSimpleUnsortedWriter sstableWriter = new SSTableSimpleUnsortedWriter(
directory,
partitioner,
keyspace,
columnFamily,
compositeType,
null,
64 );
long timestamp = 1372321637000L;
long nanotimestamp = timestamp * 1000;
long k1 = 5L;
long k2 = 10L;
sstableWriter.newRow( bytes( k1 ) );
sstableWriter.addColumn( compositeType.builder().add( bytes( k2 ) ).add(
bytes( "created" ) ).build(), bytes( timestamp ), nanotimestamp );
sstableWriter.close();
