Luís Ferreira commented on CASSANDRA-2231:
------------------------------------------
Hi,
I've patched a 0.7.9 version of cassandra with this patch plus the one on
CASSANDRA-2355, and got no errors, but when running it I get:
{code}
Invalid access of stack red zone 0x100401fe8 rip=0x1010c8f5e
{code}
I create the column family as so:
{code}
CfDef base_columns_cf_definition = new CfDef();
base_columns_cf_definition.setName("BaseColumns_CF");
base_columns_cf_definition.setColumn_type("Standard");
base_columns_cf_definition.setComparator_type("CompositeType(BytesType,BytesType)");
base_columns_cf_definition.setKeyspace("Table"+this.getContainerid())
{code}
I would really like to have this feature, but I cannot upgrade to version
0.8.1. What am I doing wrong?

> CompositeType is a custom comparer that makes it possible to create
> comparable composite values out of the basic types that Cassandra currently
> supports, such as Long, UUID, etc. This is very useful in both the creation
> of custom inverted indexes using columns in a skinny row, where each column
> name is a composite value, and also when using Cassandra's built-in secondary
> index support, where it can be used to encode the values in the columns that
> Cassandra indexes. One scenario for the usage of these is documented here:
> http://www.anuff.com/2010/07/secondary-indexes-in-cassandra.html. Source for
> contribution is attached and has been previously maintained on github here:
