> HI,
> I cannot query using DynamicCompositeType. 
> And this is how it is define the column family:
> DynamicCompositeType (l=>LongType,t=>TimeUUIDType,s=>UTF8Type,S=>UTF8Type(reversed=true),L=>LongType(reversed=true),T=>TimeUUIDType(reversed=true))
> this code is from the project countandra:
> csdb.createColumnFamily(
> 				CassandraStorage.s_keySpace,
> 				countandraCF,
> 				"UTF8Type",
> 				"DynamicCompositeType (l=>LongType,t=>TimeUUIDType,s=>UTF8Type,S=>UTF8Type(reversed=true),L=>LongType(reversed=true),T=>TimeUUIDType(reversed=true))",
> 				"CounterColumnType");
> you can get the code for test from:
> https://github.com/milindparikh/Countandra
> The Hector api is calling the same column family with data and it is WORKING FINE, the issue is only when I am trying to use CQL to query the table "ddcc".
> NOTE: the project is using cassandra 1.0.1, I updated it to cassandra 2.0.2
> If I try something like:
> select * from ddcc; 
> Error get trying to query a table that have a DynamicCompositeType
> ========================================
> cqlsh> use countandra;
> cqlsh:countandra> select * from ddcc;
