¿Cómo creo una tabla con claves compuestas utilizando el cliente astyanax? Por ahora lo he creado con cqlsh -3, y así es como se ve en cli:

[default@KS] describe my_cf;
    ColumnFamily: my_cf
      Key Validation Class: org.apache.cassandra.db.marshal.UTF8Type
      Default column value validator: org.apache.cassandra.db.marshal.UTF8Type
      Columns sorted by: org.apache.cassandra.db.marshal.CompositeType(org.apache.cassandra.db.marshal.TimeUUIDType,org.apache.cassandra.db.marshal.UTF8Type)
      GC grace seconds: 864000
      Compaction min/max thresholds: 4/32
      Read repair chance: 0.1
      DC Local Read repair chance: 0.0
      Replicate on write: true
      Caching: KEYS_ONLY
      Bloom Filter FP chance: default
      Built indexes: []
      Compaction Strategy: org.apache.cassandra.db.compaction.SizeTieredCompactionStrategy
      Compression Options:
        sstable_compression: org.apache.cassandra.io.compress.SnappyCompressor

Así es como esperaría que estuviera en cqlsh:

 CREATE TABLE my_cf (
                   ... key text,
                   ... timeid timeuuid,
                   ...   flag boolean,
                   ...   data text,
                   ... PRIMARY KEY (key, timeid));

Lo tengo trabajando con una clave compuesta almacenada como un blob, lo cual es un problema.

mi código

public class MyKey {
    @Component(ordinal=0)
    private String key;
    @Component(ordinal=1)
    private UUID timeid;
 //...
}

CF

public static ColumnFamily<MyKey, String> MY_CF = ColumnFamily
        .newColumnFamily("my_cf",
                new AnnotatedCompositeSerializer<MyKey>(MyKey.class),
                StringSerializer.get());

Kansas

                ksDef = cluster.makeKeyspaceDefinition();

                ksDef.setName(keyspaceName)
                        .setStrategyOptions(keyspaceOptions)
                        .setStrategyClass("SimpleStrategy")
                        .addColumnFamily(
                                cluster.makeColumnFamilyDefinition()
                                        .setName(MY_CF.getName())
                                        .setComparatorType("UTF8Type")
                                        .setDefaultValidationClass("UTF8Type")
// blob if no key validation class specified
// and something looking as a string if I use this:     .setKeyValidationClass("CompositeType(UTF8Type, TimeUUIDType)")
// anyway there's a single column per composite key

                                        .addColumnDefinition(
                                                cluster.makeColumnDefinition()
                                                        .setName("flag")
                                                        .setValidationClass(
                                                                "BooleanType"))
                                        .addColumnDefinition(
                                                cluster.makeColumnDefinition()
                                                        .setName("data")
                                                        .setValidationClass(
                                                                "UTF8Type")));
                cluster.addKeyspace(ksDef);

mutación

            MutationBatch m = ks.prepareMutationBatch();

            for (char keyName = 'A'; keyName <= 'C'; keyName++) {
                MyKey myKey = new MyKey("THEKEY_" + keyName, TimeUUIDUtils.getUniqueTimeUUIDinMillis());
                ColumnListMutation<String> cfm = m.withRow(MY_CF, myKey);
                cfm.putColumn("flag", true, null);
                cfm.putColumn("data", "DATA_" + keyName, null);
            }
            m.execute();

cqlsh: KS> describe columnfamily my_cf;

CREATE TABLE my_cf (
  KEY blob PRIMARY KEY,
  flag boolean,
  data text
) WITH ...

cqlsh: KS> select * from my_cf;

  key                                                      | flag | data
----------------------------------------------------------+--------+---------

cqlsh: KS> select * from my_cf where key = 'THEKEY_B' se ordenan por timeid desc;

Bad Request: Order by on unknown column timeid

¿No se ve bien en cassandra-cli abajo? ¿Por qué no funciona en cqlsh?

cassandra-cli] list my_cf;

RowKey: THEKEY_B:09f29941-e3c2-11e1-a7ef-0022191ad62b
=> (column=active, value=true, timestamp=1344695832788000)
=> (column=data, value=DATA_B, timestamp=1344695832788000)
