>From src/java/org/apache/cassandra/db/marshal/CompositeType.java /* * The encoding of a CompositeType column name should be: * <component><component><component> ... * where <component> is: * <length of value><value><'end-of-component' byte> * where <length of value> is a 2 bytes unsigned short the and the * 'end-of-component' byte should always be 0 for actual column name. * However, it can set to 1 for query bounds. This allows to query for the * equivalent of 'give me the full super-column'. That is, if during a slice * query uses: * start = <3><"foo".getBytes()><0> * end = <3><"foo".getBytes()><1> * then he will be sure to get *all* the columns whose first component is "foo". * If for a component, the 'end-of-component' is != 0, there should not be any * following component. The end-of-component can also be -1 to allow * non-inclusive query. For instance: * start = <3><"foo".getBytes()><-1> * allows to query everything that is greater than <3><"foo".getBytes()>, but * not <3><"foo".getBytes()> itself. */
Or am I missing the fact that you are inserting with cql3 as well?
